[This review was collected as part of a promotion.] My wife and I are melatonin users and recently tried Natrol time release tablets. I can definitely say that this product gave me the much needed sleep I have been trying to achieve. I would have given this product a 5 star rating, except that I would wake up in the mornings a bit groggy and tired. Once I adjusted my time on taking it, I did wake up more refreshed, but still had the effects hanging on. I can say that I am a difficult one to fall asleep because my mind races all the time. Natrol was able to relax me enough for my mind to relax and I could drift on to sleep. The best part is I was able to stay asleep and if I did wake up, I was able to get comfy and fall asleep again.
