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.

Definitely helps me feel more ready to get out of bed in the morning. Have to calibrate what time to take it; I’ve generally found erring on the side of later (as close to bedtime as possible) is best.

Makes a huge difference in waking up.
It's really helpful. It's easier to get up in the morning for sure. However, occasionally I do wake up in the middle of the night about 5-6 hours after I take it and am wide awake. So I think occasionally I digest the pill faster than ideal. Not sure how to prevent that though. I'll still be buying more though.

Literally, a game-changer for me. The grogginess and "ughhhh fog" that I usually wake with..gone. To be clear, I don't wake up "energized" but I wake up feeling like okay, I can think clearly and clearly, its time to get up. This might sound or seem simple to alot of people but its life changing for me and my day.

Sleep schedules reset.
This little magic caffeine pill has really reset my natural sleep/wake rhythm. I rarely set an alarm clock anymore, I get great sleep scores (and feel rested!) I've been an early adopter, and it's better than ever. I'm happy I stuck with it!

I Wanted to Love It, But Convenience Wins
I like the concept and, on the occasions I remembered to take it correctly, I noticed some genuinely good results. It gave me a nice boost and I woke up feeling more energized.
My biggest issue is the timing. I tend to eat late, and since you’re not supposed to take it with food, I often realize I’ve missed the window and end up skipping it altogether. That makes it difficult to build into my routine.
The other factor is convenience and value. Lately I’ve been using caffeine/energy pouches that I can simply pop in my mouth whenever I need them. They provide 100 mg of caffeine plus other focus and energy ingredients, work almost immediately, require zero planning, and cost significantly less.
I still think Zest is a good product and the idea behind it is solid, but for my lifestyle the extra planning and higher cost make it hard to justify over a more convenient alternative. If it were more affordable or easier to fit into a flexible schedule, I’d be much more likely to use it regularly.

Better than you think!
It makes the thought of waking up not so miserable! The difference is noticeable and I certainly know when I don’t take it. I’m a believer!

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.

Makes Early Mornings Easy
I’ve been using Zest for a couple of months. Honestly I wasn’t sure if it was working at first, but a couple of months out I can tell the difference when I don’t take it. I wake up at 5:00AM, and the days when I haven’t taken Zest the night before I’m dragging. On the mornings when I haven’t taken Zest the “fog” isn’t there and I can get up and do what needs to be done for my day.

It's not a lot of caffeine, but it does help with feeling groggy in the morning.

Really enjoy the extra boost in the mornings and with wake up inertia. I use this everyday because I am not a morning person but this makes it better.
