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.

Love it!!
My husband and I love Zest! We take it every weeknight, and the biggest difference we’ve noticed is how much less groggy we feel when we wake up in the morning. Mornings just feel easier, and we feel much more ready to get up and start the day. It’s become a staple in our nightly routine!

Skeptical, at first
My wife and I were skeptical at first. Then we missed a day, and could tell a substantial difference in our energy in the morning. Great product.

Pleasantly Surprised
I honestly had pretty low expectations given that I’m not a fan of caffeine pills—yet combined with the L-Theanine I definitely had less trouble waking up.

I can’t believe how…
I can’t believe how well this works and how it has changed my life! I’m serious, I would wake up in such a funk and felt horrible. I couldn’t think straight, I felt hungover, I was irritable, and I just couldn’t wake up and get going. I was always waking up from either a deep sleep or REM sleep. I read about how this works, the science, and it really makes sense and obviously works. I wake up feeling normal, like I’m supposed to, and even better with some actual energy and cognition! I don’t dread waking up anymore at 6:30 for work. I can actually use my mornings for things I want to do instead of sitting there like a zombie. Real customer here, not paid, and definitely recommend!

Great but 10h release time would be better
I wish it released more than 8h later. This way you could have more flexibility of when you take it vs bedtime vs wake up time.

I like the idea...
I like the idea of it, however I'm not sure if it contains enough caffeine for me to notice a difference when I wake up
