Customer Ratings & Reviews

Sleep Tonight is rated 4.6 out of 5 by 11.
Rated 4 out of 5 by from Sleep General For sleep, I would generally think of multiple substances. The item "Sleep Tonight" is one of the few that suffice alone. Its constituents, of which there are at least ten, make up enough.

Rated 5 out of 5 by from Good sleep aid It works well for me. I have been using it for a year or so. I always keep a bottle in stock.

Rated 5 out of 5 by from Helps me wind down... This supplement does not make me fall asleep, but it is a huge help in relaxing and winding down for bed. I have had trouble falling asleep for years, and following a good evening routine and using Sleep Tonight has solved the problem. It does not cause crazy dreams or morning grogginess; this is a big improvement over other products for sleep. If you are stressed and "wound-up" at bedtime, I highly recommend it.

Rated 3 out of 5 by from Did not improve quality of sleep I have used products made by Enzymatic Therapy and have never been disappointed until using this one. This product did not help me sleep at all. In fact, when I took it, I was relaxed all night, but never drifted into a deep sleep. For whatever reason, it had the opposite effect on me that it should have. For that reason, I will not purchase it again.

Rated 5 out of 5 by from good sleep One of the best I've tried, even if I did wake up I went back to sleep easily.

Rated 5 out of 5 by from An excellent product for giving a little extra edge in getting to sleep.

Rated 4 out of 5 by from Works well I like this product a lot. I have trouble "shutting off" my brain at night, but this seems to help. My biggest disappointment with it is the packaging. There are only 28 pills (more would be nice), but they come in an enormous bottle. The pills don't even fill a quarter of the bottle. It's a shame and a waste. But the product does what it claims to for me.

Rated 5 out of 5 by from Great sleep remedy! I have tried many natural sleep remedies and this is one of the best. It even helps me sleep if I have consumed caffein or some sugar, both which tend to keep me awake. Another Enzymatic Therapy product that I use with it is the "Fatigued to Fantastic" sleep remedy formula capsules.

Rated 5 out of 5 by from In Love With This Product I have trouble falling asleep and staying asleep due to the stress in my life. This product helps me relax so I can fall asleep more quickly. It also helps me go back to sleep when I wake up during the night.
