Life-changing Aid For A Heavy Problem Drinker
I’ve had intense anxiety (social and general) for as long as I can remember. Years ago I turned to alcohol to help—a couple of drinks when I felt anxious, or before a social situation calmed everything down, and I felt as though I could manage. But it quickly spiraled out of control to the point where I wasn’t drinking and getting drunk, but instead “dosing” throughout entire days and evenings. The moment I’d try to stop the world would come crashing down and it became a choice between feeling “normal” by drinking something, or dealing with nonstop racing heart, shortness of breath and severe depression. Well the latter was absolutely horrible to live with, so I kept choosing the former. I was hiding liquor bottles in the house so I could pop back to a room and take a nip the moment I would start to feel overwhelmed. Obviously this wasn’t sustainable. My epiphany occurred when my senior dog had a seizure, and to cope, I begged my partner to go and pick up a pint of alcohol, just to get through the worry and fear (she’s okay now). I realized SOMETHING had to change. I read and did research and decided to try L-theanine. This brand was the first brand I tried. I began with 2, and then upped the dose each day until I found the perfect “sweet spot” for me at 1200mg*. That seems like a lot, but my brain had been depleted of natural anxiety defense for years. The day I took at the amount for the first time changed the entire course of my future. For once I was able to breathe, to think clearly, to feel calm and normal without a drop of alcohol. The effect lasted nearly 12 hours, and that night I slept like a baby. I tried it the next day, when that familiar anxiety and urge to drink crept up... and it worked again. Within the hour, my heart began to beat normally, and I was calm and content, and once again drifted off to sleep that night genuinely looking forward to waking up (a rare thing when you drink every night). So far I’ve been sober for three weeks, and I feel amazing. There are no sedation, stimulating or uncomfortable side effects, it kicks in within 30-60 minutes (depending on whether you’ve eaten), and one dose lasts me 12+ hours. I have zero urge to drink, I sleep great, my mood is amazing, and my typical ADHD brain is clear and focused! It’s my belief that when my brain finds equilibrium and begins to produce its own dopamine again (which I’ve read takes about 6 months for alcoholics and problem drinkers) that I’ll only need the L-theanine on difficult or stressful days. For someone who spent every waking moment suffering the pain of severe anxiety, I could really cry from joy for this mental, physical and emotional reprieve. For once I’m truly excited about the future. *1200mg is a high dose, and over the recommendations based on studies looking at changes in alpha waves (200-400mg). I am not a doctor or health practitioner, nor am I suggesting people follow my dosage right out of the gate. If you’ve never had substance abuse issues, you likely will not need such a high dose. Research and consult your doctor before adding any supplement, especially if you intend to take more than the recommended amount. I began with two (the highest recommended dose) and did not increase that dose until 24 hours later. I stopped at 1200mg because that was the dose that gave me the relief and results I was looking for; I do not intend to exceed that amount for myself in the future. Edit to Update: it’s over a year later, and I no longer drink, nor do I need to take Theanine (even in social situations!). My brain is clear, I’m genuinely happy, and so so glad I discovered this. Quitting drinking can be hard, but this absolutely saved my sanity and my life. I still will always keep a bottle on hand, and I can’t recommend it hard enough for folks desperately looking for aid. Good luck out there friends!

Works great !! Very Satisfied !!
I am very satisfied with The L-Theanine 200 mg . I actually bought it to take in the morning but I had to switch to night time because it really relaxed me and made me too tired. I’m happy to say I’m finally sleeping. I would wake up around 3:00 AM off and on until 6:00 am when it was time for me to wake up. I felt exhausted all day. I had no energy and was in bed for 7:30 pm . I have been taking this supplement for a week and I feel so much more energized during the day because I’m getting restful sleep. I feel by brain is finally shutting off which has been a struggle for me. I will definitely keep ordering this supplement. I will also say you can tell it is great quality because you can smell them when you open the bottle.

Great for calm focus — I’ve been using it almost a year
I’ve been taking this for almost a year and it’s been consistently helpful. I take it with my morning coffee before work and it keeps me relaxed and focused without the caffeine jitters. It also mixes smoothly every time, which I really appreciate. Plus, the brand feels very natural and organic. A simple, steady way to start my day feeling more Zen.

Love it, you need this if your stressed!
I've use this supplement consistently, I am now on my last pill and Im ready to order another bottle. This has been a game changer, I noticed my eye was twitching from stress related to working with preschoolers. Within a week the twitch was gone!! I'm trying to keep my nervous system functioning & this has kept me sane it's not something you feel coming on strong but you know it works! No taste, no upset stomach, no order so easy to swallow. Please try!

If you like a morning coffee, add this
Great stuff, love it with a cuppa joe. Makes me alert, but relaxed with that combo. Kind of middle of the price range, there are some more expensive and less, but I don't trust the stuff that is dirt cheap. Google says suntheanine is patented top tier stuff, and I agree.

This supplement definitely works
I just recently discovered this supplement and I’m amazed at how well it works. I actually take it when I have an espresso or caffeinated energy drink and it keeps the jitters at bay. It promotes calm and focus at the same time; would recommend even just for a natural way to combat anxiety.

The magic pill for sure! The best product!
So, let me start off by saying how this product is seriously such an amazing one! I am so glad that I tried and love it! Here is a little background about myself... I suffer from really bad migraines and tension headaches (at least twice a week from 3-4 days), basically almost most of my weekdays, due to stress from work. It was at the point that I would come home, shower, and go to bed (avoiding everything, including my own family). This was really at the point that it would prevent me from doing the things that I enjoy and even taking care of my kids. To make my long story short, I tried a variety of things to see what could help, including acupuncture, seeing a chiropractor, migraine prevention and emergency pills, change in my diet... and nothing helped. The emergency pill does help, but only for the moment and the pain usually comes back again within 24-36 hours after taking it. I got to the point that my neurologist prescribed me to try something that only brought out the worst side effects on me that I had to take a few days off as it affected my nervous system. I freaked out and felt like I was running out of options and that these headaches were ruining my life completely... until I started researching for natural supplements and I came across this amazing product. After reading and checking out some reviews, I decided to order a bottle and give it a try (I mean, what could I lose at this point?!...). Let me tell you that since the second day that I started taking it, I have been feeling the goodness of this product; the magic! It has been over 2 weeks already, and I have only gotten one mild migraine (yes, only on migraine within the last two weeks) which this never happened before. Definitely reducing the number of migraine episodes that I get. I take it at night, right before bed, and I wake up easily, feeling energized, clear minded, and focused. I’ve also noticed that I am more focused and I don’t get as stressed as I was compared to before taking it. I feel like this helps me staying relaxed but focused. Not groggy at all! I even told one of my coworkers who also suffers from migraines to give this product a try since it worked for me. I’m no doctor whatsoever, but this was definitely worth the try. I plan on continuing taking this and even buying more bottles of L-theanine. Moreover, I highly recommend it! The quality of the product is great and I don’t get any after tastes. I look forward to less headaches (as it’s heloing me at the moment) and hope that it continues working.

I love it! Helps my anxiety
I’ve been taking this for about 3 years, and it has truly helped with my anxiety. I’m a 39-year-old woman in perimenopause with ADHD, and when I take this consistently, I notice a big difference in how calm and balanced I feel. If I miss it for a couple of days, my anxiety definitely feels worse. I will go days even weeks without noticeable anxiety, it’s amazing for me! It doesn’t completely erase anxiety, but it helps enough that I really hate forgetting it. I take it in the morning with my omegas and my ADHD medication with no issues. I don’t know why this isn’t prescribed more often, but for me, it’s been amazing. Everyone’s experience is different, but this has made a noticeable positive impact on my daily anxiety.
