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.

Absolute game changer for sleep inertia
These pills have changed my life. I have suffered from sleep inertia for my entire adult life, since puberty. It has gotten worse as I have gotten older. These pills are the only thing that ease my anxiety enough to know I will wake up when my alarm is set the next morning and actually get out of bed. I don’t find they have completely reset my circadian rhythms and suddenly made me a morning person who can get up at 5 or 6 in the morning. I also have found they are more effective when I *don’t* take them every night, as my body gets used to them quickly and therefore will override them and stay asleep. All that said — when used in the way I’ve found works best for my body, these pills have been a lifesaver. I am so grateful to have them for when I need them.

Improved Sleep Inertia
So far it is helping a bit. I still struggle a little in the mornings, but before, I could sleep through my alarm for over an hour. Now I actually wake up to my alarm, but I still feel a little bit groggy and tired. I'm assuming this will get better over time, but honestly, just being able to wake up is a huge improvement to me. I do wish they had a little bit more oomph though. Caffeine is not as strong for me as it is for others, but the other ingredients are probably helping with that. I do still feel like I need to take my Adderall in the morning. I'm not AS tired throughout the day as I usually am. If there was a stronger version for people who aren't sensitive to caffeine, I would definitely buy it! Or maybe take three instead of 2 before bed? I won't do that before looking into if it is okay to do though. I'm hoping it just gets better as I continue to take them!

Early Mornings Made Easy
Zest has really helped me get up and start my day earlier than ever. I’d always hit snooze on my alarm several times before getting out of bed, but now I can get myself up on the first alarm without feeling super groggy. I’ve even started working out in the morning, which I rarely could do before. Can’t recommend this enough!

Life-changer
Works as advertised! They definitely wake me up and i feel instantly alert, versus being groggy. When I take zest I don’t have the urge to snooze or go back to sleep. I do wish the price was a tad lower, and there was an option for different strengths. Still a 10/10.

Am I now a morning person?
I never was a morning person, but Zest has helped me beat my alarms and wake up with more go, and less grogginess. Excited to see how I continue to be impacted by Zest!

Zest = LIFE CHANGING
Zest has been life changing for me. I struggle so badly with waking up in the mornings that I’ve been on seriously thin ice at work. Zest changed that for me. I wake up feeling refreshed, recharged, and ready to go when I take Zest. For me personally I’ve found the best time to take it is at 9:30 PM. Sometimes I even take 3 instead of 2 for that extra boost. Think natures adderall - without the crash. Specifically formulated for morning wake ups. I can still have coffee with my zest and feel fine. Zest does more than just put pep in my step. It allows me to be a better human being. I’m thriving with Zest and highly recommend it to anyone else who struggles with severe morning grogginess and/or sleep disorders!

Game changer
Zest has been a total game changer for me. I take it before bed, and I actually wake up feeling alert (sometimes even before my alarm) which I love. No grogginess, no jitters, just clean, steady energy that makes mornings effortless.

Someone wake up Green Day
Novel approach to a common problem. Delayed release caffeine has been a game changer for me. I've gotten a night time centric rhythm thats caused me to be very groggy and sleep in during the mornings, though this isn't conducive to my job. Zest gives me a boost for the morning and with their new version including L-theanine, fights off jitters and anxiety, so I wake up with a calm burst of energy. You can control the dosage as well if you only need a small boost. They are on V2 a month in to my subscription and there is no increase in price which I appreciate. This is a company who is experimenting to find their final product and I'm hear for it.
