Sixteen years of a prescription sleep aid trashed my liver. I have struggled for the three years since I had to stop taking it. My problem is staying asleep from 4:30-7:30 as my schedule necessitates being awake late. After eliminating blue light at night as much as possible and making sure I was thoroughly hydrated I was still having problems. This product really worked for me after trying many others that did not. I still awaken several times towards morning but I quickly go back to sleep instead of having to wait hours. Once in a while If I am not careful of my blue light exposure I will still have the problem. In that case, I take one more of these pills and read for a half hour or so until I conk out again. I am praying I do not become immune to the effectiveness of these amazing pills but I am now purchasing my fourth bottles. We shall see. I am certainly relieved.
