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.

Perfectly Balanced
It works perfectly! I took it around 1030pm. Roughly 2hrs after eating. I shot straight up at 6am ready to rock and roll! Didn't even need the alarm. Then I had steady energy the rest of the day. No crash. 100% recommend

Clever and Legit
This is has actually been a game-changer for me. I’m a coffee addict and the time between waking up and getting caffeine into my system is pretty miserable. This totally eliminates that and I’m drinking much less coffee overall. I also have a lot of anxiety about sleeping through alarms when I have something important. Taking these little puppies before bed is such peace of mind that by the time my alarm comes around, I will either already be awake, or have no problem waking up to it.

Works like a charm. I've always struggled with being an energetic morning person. Zest woke me up on the right side of the bed earlier than ever, ready to tackle the day. Couldn't be happier. Customer for life. THANK YOU!!!

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.

A year on Zest
I’ve been taking Zest for about a year now and I have to say it has truly made an impact to my life. I’ve been a very good sleeper my entire life, to put it simply. It’s always been difficult for me to wake up in the morning and I’ve never been a morning person. Now, I wouldn’t say this has turned me into a 5am person but my energy levels and ability to wake up to my first alarm have been improved drastically. I do not experience any negative affects from the caffeine when taken at nighttime either. Absolutely love Zest and it is part of my daily regimen!

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!

Life changing product
I never write reviews, but as skeptical as I was - this pill has genuinely changed my mornings!! I’ve done the sleepy time routines, melatonin, caffeine in the morning and nothing has helped until I found Zest!
