I've had trouble sleeping for about 8 years. I take a prescription sleep aid. I cut them in half. But 1/2 or even a whole one I only sleep 4-5 hours at a time. I can trace it back to the time I was diagnosed with Fibromyalgia. I also take Ultram 4 times a day for it. Sometimes I can't even move or the pain is so bad I can't sleep. You don't mention how old you are. There may be other reasons why you aren't sleeping. Menopause can also affect your sleeping patterns. It's best to let your Dr know whats going on. Over the counter drugs can affect other drugs that you may be taking. *(Adverse reactions) I was married to a male nurse for 13 years and just graduated in the Health Info Tech field last year. Be very careful.
