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.

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

Welcome Change
For, me, a lifelong groggy person with a serious case of sleep inertia, Zest is a life-changer! On the first day, I woke up exactly after 8 hours of sleep—with a clear head, no grogginess, no bad dreams lingering for the day, and in a cheerful mood. This NEVER happens. And now on my fifth day with the same result, I am convinced. Zest really works.

30 days in, and I’m waking up ready—Zest Wake‑Up Pill is delivering
I've been using the Zest Wake‑Up Pill for about 30 days—and it works exactly as promised.
Take one capsule before bed (preferably on an empty stomach), and around 7–8 hours later, the caffeine releases—right when you’re waking up. No groggy snooze cycles. Just clean energy delivered at the perfect time

Off to a good start!
I have taken Zest for two nights now and I have felt more energetic upon awakening both following mornings. I have not felt any negative caffeine effects, such as jitteriness. So far so good!

It's kinda weird. ...
It's kinda weird. You think "caffeine" and you think jittery, wired... With Zest, i wake up suddenly and alert. not at all shaky or tense. Just "up." And because of that, I don't have that anxiety about "am I late? what do I need to do?" I just get up. That is the goal. It offsets a lot of morning stress to wake up feeling like that.
