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.

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.

The solution to morning grogginess!
Just the right amount of caffeine and l-theanine for energy to wake up without worrying about a crash later. No more negotiating with the snooze button in the morning - I just wake up every morning feeling great!

This is the kind of Innovation science was made for!
I was skeptical at first, but this little pill is life changing! I always used to wake up groggy, no matter how much sleep I got, and coffee barely helped. So how much good would a single caffeine pill be? Well it's So much help! First the effects seemed mild. I was getting a lot of sleep, so I thought maybe I was just finally feeling more rested on my own...or maybe it was just a placebo effect? But then I accidentally skipped about 3 days in a row - and Wow did I noticed the difference! I wake up naturally now, feeling normal - but Rested and Not Groggy. It even Physically helped by significantly shrinking my swollen and puffy morning under eye bags! I Love Zest!!

I’m Waking Up Feeling Clear and Alert
I’ve been taking the Wake-Up Pill for a while now, and it’s made a huge difference. I wake up feeling clear and alert, without that heavy, groggy feeling I used to have in the mornings. I highly recommend.
