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!

This supplement has been a true game changer! It works as promised with zero side effects -- just a more alert morning without the early morning fog and grumpiness.

Literally, a game-changer for...
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.

Made me a morning person!
I have never been a morning person - always struggling with brain fog when I woke to my alarm. Zest changed that and now I wake with the energy I need to jump start my day

One of the cheat codes of life...
It actually works. Ive wanted to not feel groggy in the mornings for years (even with getting 9 hrs of sleep every night). With this pill its so much easier to get out of bed. It takes away that tiredness. I highly recommend. The serving is 2 tablets but I usually just take 1 of them.

Absolute game changer for sleep inertia
These pills have changed my life. I have suffered from sleep inertia for my entire adult life, since puberty. It has gotten worse as I have gotten older. These pills are the only thing that ease my anxiety enough to know I will wake up when my alarm is set the next morning and actually get out of bed. I don’t find they have completely reset my circadian rhythms and suddenly made me a morning person who can get up at 5 or 6 in the morning. I also have found they are more effective when I *don’t* take them every night, as my body gets used to them quickly and therefore will override them and stay asleep. All that said — when used in the way I’ve found works best for my body, these pills have been a lifesaver. I am so grateful to have them for when I need them.

Still not a morning person, but no longer a groggy, oversleeping ogre.
For my entire life I've had trouble getting up and being a productive, normal human in the mornings despite having plenty of restful sleep the night before. Zest has changed my life. I am not magically now a go-getter pleasant morning person now, but it doesn't feel so impossible to get up and get moving. I am no longer groggy and sluggish when my alarm goes off. In fact, I have been able to regulate my sleep schedule much better and often wake just before my alarm rings.

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!

Don’t be skeptical. GET IT!!
I was very skeptical about this product but got it just to see. I struggle so bad in the mornings. I cannot believe how much of a difference Zest has made for me. I have 2 kids and they are my alarm clocks and I have been MUCH MUCH less groggy, irritated and just feeling like I cannot keep my eyes open!! It’s amazing! I definitely recommend this!!! It has really changed my life around.
