Worked as advertised, but word of warning!!
If you take any SSRI medication, taking L-Theanine as well may increase your risk of seratonin syndrome, a rare but extremely serious condition. If you take any serotinergic medication like SSRIs (Lexapro, Prozac, etc.), MAOIs, or TCAs, make sure you understand the risk and know the symptoms of seratonin syndrome when taking any supplement with L-Theanine.
A lot of people taking SSRI's have trouble waking in the morning and would benefit immensely from this product, so I hope Zest Labs releases a secondary version without L-Theanine so we can feel safe and comfortable taking it every day. At the moment I am only taking one pill (40mg caffeine, 40 mg L-Theanine) out of caution, but I wish I could take a full 80mg caffeine.

“Waking up after 7 hours like clockwork”
From Day 1, Zest has consistently worked in 7 hours for me. I'm still figuring out the timing and if I want to be a morning exerciser before getting ready for work, but I'm waking up less groggy and more able to plan and make decisions. I used to wake up well before I needed to be up in order to have multiple alarms and a slow morning to let the coffee hit. Taking Zest is already a big improvement for a night owl with an early morning job. My only issue is sometimes I want more than 7 hours of sleep, but it will wake me up after 7 hours. So it's hard to take daily, though I know that is how it works best. I'm going to try to take it at 10PM even on weekends to wake up at 5AM and hope those habits become regular during the workweek. I've been waking up a few minutes before my alarm every day, so it's not a surprise.

“Got me off provigil”
so I have idiopathic hypersomnia, and it has been getting increasingly worse in the last year. I was taking Provigil 200 mg twice a day and I was still having issues staying awake. Unfortunately, the Provigil put me in afib so taking more wasn’t really an option. My provider found this for me, and I started taking it in place of the provigil. It was a rough transition at first because I was also on propranolol. But after about a week, it helped me tremendously. Now I take two of these at night and I actually feel awake enough to drive to work. It’s safer because I don’t go into AFib anymore.

Improved Sleep Inertia
So far it is helping a bit. I still struggle a little in the mornings, but before, I could sleep through my alarm for over an hour. Now I actually wake up to my alarm, but I still feel a little bit groggy and tired. I'm assuming this will get better over time, but honestly, just being able to wake up is a huge improvement to me. I do wish they had a little bit more oomph though. Caffeine is not as strong for me as it is for others, but the other ingredients are probably helping with that. I do still feel like I need to take my Adderall in the morning. I'm not AS tired throughout the day as I usually am. If there was a stronger version for people who aren't sensitive to caffeine, I would definitely buy it! Or maybe take three instead of 2 before bed? I won't do that before looking into if it is okay to do though. I'm hoping it just gets better as I continue to take them!

More, better, constant energy
I feel so much more energy now throughout the day! And it's not in peaks like with coffee, it's constant instead. It's also got rid of my grogginess when I wake up, which feels really good. Definitely recommend!

Welcome Change
For, me, a lifelong groggy person with a serious case of sleep inertia, Zest is a life-changer! On the first day, I woke up exactly after 8 hours of sleep—with a clear head, no grogginess, no bad dreams lingering for the day, and in a cheerful mood. This NEVER happens. And now on my fifth day with the same result, I am convinced. Zest really works.

This is the kind of Innovation science was made for!
I was skeptical at first, but this little pill is life changing! I always used to wake up groggy, no matter how much sleep I got, and coffee barely helped. So how much good would a single caffeine pill be? Well it's So much help! First the effects seemed mild. I was getting a lot of sleep, so I thought maybe I was just finally feeling more rested on my own...or maybe it was just a placebo effect? But then I accidentally skipped about 3 days in a row - and Wow did I noticed the difference! I wake up naturally now, feeling normal - but Rested and Not Groggy. It even Physically helped by significantly shrinking my swollen and puffy morning under eye bags! I Love Zest!!

30 days in, and I’m waking up ready—Zest Wake‑Up Pill is delivering
I've been using the Zest Wake‑Up Pill for about 30 days—and it works exactly as promised.
Take one capsule before bed (preferably on an empty stomach), and around 7–8 hours later, the caffeine releases—right when you’re waking up. No groggy snooze cycles. Just clean energy delivered at the perfect time
