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.

This supplement is amazing!
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.

Works like a charm!
I bought these for my boyfriend because he’s been feeling sluggish and exhausted when he gets up for work. He says there’s a noticeable difference when he takes them and waking up is a lot easier. He feels more energized throughout the day than he used to, and he doesn’t experience a crash when they wear off.

Can Finally Wake Up Easily
I have fatigue problems, and they result in me really struggling to transition from sleep to wakefulness. Zest is the first solution I’ve found that allows me to have a mostly normal morning without sleeping through alarms and feeling horrible and unrested immediately when I wake up. The formula helps the boost to not be such a jolt, I don’t feel forced awake or anything - it actually makes my wake-up process smoother.

I liked that it actually works
I liked that it definitely works; I always have a hard time waking up and after a few days of taking this I can confirm it works.

If you wake up feeling groggy…this is your solution. No bs.
My buddy knows the founder & told me about the product pre-launch, I was instantly intrigued & excited…as someone who always wakes up feeling groggy, even after a good night’s sleep, due to a benzodiazepine prescription, taking melatonin and occasionally sleeping aids, etc., something like this was like a dream product, & I can vouch for it. This is an incredible idea & impeccable execution, I wake up feeling fantastic and ready to go, and even after nights out where I’ve had some drinks, perhaps other things haha, these work magic. Highly recommend, and congrats on a successful launch!
