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

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.

Works like a charm.
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!!!

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

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

Works well to wake up refreshed and less tired
On my 3rd day of using Zest. So far it’s working well for me. I’m sleeping well and waking up feeling less tired and with more energy. The only downside I’ve noticed is that I’m getting a little additional sweating in my armpits about 15 mins after waking up. Nothing too heavy , but more than usual.

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!
