Yes, I did use it for several years. Worked well for me then, bam, it stopped working, so took 2 and that helped for a long time, then stopped working. Then went to one of the PM's, which worked a couple years, then same story, layed awake again. Finally told my DR, he prescribed amatriptyline, 25mg. Works like a dream. You are not groggy the next day and feel very refreshed in the morning. It is a mild sedative, cheap, and is not harnful to you. It relaxes you and you are able to shut down at the end of the day and sleep restfully. Have used it for years and still working great. Ask your Dr about it. It is no fun not getting a decent nites sleep.
