As advertised and works for me
As advertised. Z-Quil works for me, but I heard not for all. This sleep aid is worth trying. It says non addictive but I feel like taking it every night. lol !

It does the job
I’ve been using ZzzQuil Nighttime Sleep Aid Liquid for a while now, and overall I’d give it a solid 4 stars. It definitely helps me fall asleep faster, especially on nights when my mind won’t slow down. The liquid form works pretty quickly, and I usually start feeling drowsy within about 20–30 minutes.

Makes me Zzzzz
I was a little apprehensive because of the prior reviews BUT I am so glad that I bought it. I take 30 ml and within 45 minutes, I am asleep. I wake up feeling great and with a non drowsy feeling nor do I have bad dreams that some others have experienced. The taste is actually pretty good. I thought it would taste like the god awful night quil but this was suprisingly good. Since I first bought it from Amazon, I bought 5 other bottles. It is a tad bit expensive but I normally catch it on sale up here on Amazon or you can get 2 HUGE bottles are target for 11.99. It is well worth the price but I do wonder if the claims are true about it being non addicting. I went 3 days without taking it and I "craved" more but maybe it was just MY tolerance level. Overall, I will continue to purchase this and recommend it to everyone who has sleeping troubles.

It really really works !!!
I cannot go to sleep without it . The Warm Berry flavor is not so bad and I take it about a half hour before I go to bed.

Rip off for 6oz.!
Zzzyquil is a great product. A few weeks ago I bought a double pack of 2 12 oz. bottles for $22. It was my fault for not checking the size of these bottles so I was quite pissed off to find I just spent $18 for 2 6 oz. bottles! Half the size for practically the same cost. Buyer Beware!
