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.

Definitely helps me wake up without needing to hit snooze multiple times. I feel more awake in the morning.

Makes a huge difference in waking up.
It's really helpful. It's easier to get up in the morning for sure. However, occasionally I do wake up in the middle of the night about 5-6 hours after I take it and am wide awake. So I think occasionally I digest the pill faster than ideal. Not sure how to prevent that though. I'll still be buying more though.

Does what it says!
Zest is overall I good product! I have had trouble over the years with waking up instead of snoozing the alarm until the last minute. I struggle with motivation and a sleepy feeling that lasts until afternoon but

Great Product, Hoping for Stronger Version in the Future
I love the concept and I do feel like it has helped but as a borderline caffeine addict I would like to see a stronger dose version. I know that I can just add more capsules but I already take a bunch of different medicines and would prefer to keep the Zest dose to 2 capsules with more caffeine.

What have I been doing before this?!
Absolutely have no idea how I was surviving before I gave this a shot. Worth the price mostly except I wish it lasted a little longer as I go to bed way early to be up earlier than most. I’m going on my third month. Absolutely worth a month of trying it to see if it’s for you.

Already an early riser but usually miserable
I already get up pretty early in the morning so I was nervous this would work against me. I was worried for nothing. When I wake at my usual 430 am I am ready. I don’t need the usual half hour to mentally prep myself. I am only about a week in and I’m hopeful it continues to work this well for me. I don’t feel jittery at all which was another concern. I just feel awake and that’s what I’ve been begging for. So happy about this product working as claimed.

Wakes me up in less than 8 hours
Definitely works, but doesn’t last 8 hours for me. Most of the time it wakes me up 6-6.5 hours after I take it.

Only a week in so far
I’m only a week in and I feel like on days I get up and go to work I have more clarity. Day 1 was a significant effect on my brain but each day since has not been as profound. Today I let myself sleep longer and I am more tired so still figuring it out. I’m hopeful though!

Good overall, but wish it was 9 hours instead of 8
It feels nice to finally wake up not feeling groggy...but...I wish the release timing were more like 9 hours than 8. Once I take the pill, I need to go straight to bed and try falling asleep. Instead, I'd like to take the pill and lie in bed until I fall asleep. If I take the pill too early, then I get less sleep if I don't fall asleep in time.

Works well, albeit duration is a bit short
Works, though duration is on the shorter side. I wake up feeling more awake (which is great!) but think my actual sleep duration has trended downward a bit. Overall still definitely worth it.
