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!

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.

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.

Zest is a total morning hack
I was skeptical about taking caffeine before bed, but the timed-release thing actually works the way they say it does. I’ve been on Zest for over a month now, and I’m waking up at a regular time on my own — and, the part I care most about, without the heavy grogginess I used to have. I used to need a solid 45 minutes and a coffee before I felt like a functioning person. Now I’m clear-headed pretty much from the moment I’m up.
The routine couldn’t be simpler: two capsules with a little water before bed, don’t chew them, done. My sleep itself hasn’t felt disrupted, and I haven’t had jitters or an afternoon crash.
If mornings are the part of your day you dread, this is worth trying.

This Actually Replaced My Morning Caffeine Hack
I don’t write reviews often, but this earned one.
I’ve spent years trying to hack mornings. Energy mints. Leaving a Ghost on my nightstand so I could slam it the second I woke up. I’d literally drink it and then fall back asleep until the caffeine hit.
Zest is the first thing that’s actually made me stop doing that.
I still have mornings where I crawl back into bed for a few minutes because, well…I’m human. But getting up is noticeably easier, and I don’t feel like I need to shotgun caffeine just to start my day.
It’s one of the few products where I genuinely notice when I’m taking it versus when I’m not.
Great product. Great team. Easy 5 stars

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!

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!
