What Are Our Sleepers Saying?

★★★★★

I'm still in disbelief

I've had seemingly unsolvable sleep issues for years. I've tried every possible known remedy, and some very random/questionable unknowns - to no available. After so many years - I simply resigned myself to living with chronic sleep problems (and all that goes along with that). Lo and behold - this stuff actually works. I fall asleep fast, sleep through the night, and am not groggy in any way/shape/form the next morning. Pretty amazing.

Helps me stay asleep all night

This product helps me stay asleep all night. I feel fully rested in the morning.

★★★★★

It works!

I’ve gone from sleeping 3 to 4 hours a night to now sleeping 6 to 7 hours. It may not seem like a lot of sleep to some people, but for me it’s a HUGE improvement.

Incredible Sleep Aid

Since I started using CS2, I am enjoying 7 1/2 to 9 hours of sleep per night. Thank you for this wonderful product. At 69 years old, I thought I was doomed to 5 hours a night. Not any more! I tell all my senior friends to try this and enjoy sleeping again.

It’s working!

I have tried almost every sleep supplement there is and have not been happy with any of them. I wanted to wait for two months to post my results with CS2. The first thing I want to say is that the lemon lime flavor is outstanding! And I have noticed after taking it consistently that I am getting tired in the evening (which I never was before) and sleeping about six hours. Most of the time after waking, I can get back to sleep. I have been having a sleep issues for about 15 years, soI’m not expecting miracles, but I have to say that this formula is working better than anything else I’ve taken so far. I would suggest trying it to see if it works for you.

First sleep supplement that has worked for me

I've tried so many herbals and supplements to improve my sleep quality - melatonin, valerian root, Mg, ZMA, GABA, etc. - but I'd always continue waking up 7 to 10 times each night. With CS2 I'm down to about 1 to 2 wakeups per night, and I'm usually back asleep within 5 to 10 minutes. I started feeling the affects about 2 weeks in. As long as I shut my caffeine off by 2PM it's pretty standard now that I'm going to get a decent amount of sleep on CS2. I never miss a night taking the product. They could probably sell this supplement a little cheaper than they do, but with it being the only thing that's worked to date I'll stay subscribed.

I tried CS2 Sleep drink and wanted to share my experience. It was easy to use, and I liked having it as part of my nighttime routine. Everyone’s experience may be different, but I’m glad I got to try it.

Finally! A supplement that works.

I've had trouble sleeping most of my adult life. I've spent so much money on countless supplements, and nothing really worked. My "nighttime stack" was costing almost $150 a month, it wasn't working well, and it was making me drowsy. CS2 is one supplement that doesn't make me drowsy and actually works. My sleep isn't perfect, and I am also engaging in CBT-I to reframe my relationship with sleep, but CS2 is a great adjunct with zero side effects. I'm so happy I found it! I prefer the berry flavor to the lemon-lime flavor, but both are good.
