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 buy if you struggle to wake up!
This completely took all my grogginess out of my mornings, it’s simple to take and I wake up feeling replenished and awake. 10/10 would recommend!

Great start...seeing results already.
I've been using Zest for a little while now. Still experimenting to find the right dose for me, but I love that the modular system gives me the freedom to do that, and I am already noticing positive results. I look forward to continuing and finding what works. I love that the company took customer feedback into account when crafting the 2.0 formula.

A noticeable difference!
I 100% notice a difference in my morning energy when I do take it. However, sometimes I still sleep in, despite taking two pills. Definitely try to take it on an empty stomach, as I notice that it’s more effective that way.

Great Concept and Company - Dose could be stronger
Great customer service, concept, and delayed release innovation!! I personally think they should have a stronger option, as 80mg of caffeine did not feel like quite enough.

This product is really effective.
This product is impressive. You can really feel the caffeine kick in as soon as you wake up. Rather than feeling groggy, you start the day feeling energized. I use it every day.

Noticable difference
Great energy when I wake up, only issue is consistency: if I have a particularly empty stomach when I take it, it tends to kick in 6 hours or so after, but 8 hours is the goal and it usually works around then. Noticable difference on the odd days I forget to take one

Changed my life
This has totally changed my life. It helped with my slow mornings and sleep inertia almost instantly, and remaining on Zest for several weeks has only made the benefits clearer.
