insomnia
"I was taking this medication on and off for over a year. Although it did help me go back to sleep,  I found myself going to the doctor more and more for constipation, stomach pain, muscle pains, anxiety and the worst one tingling all over my body. I went through all sorts of miserable medical tests, and everything came back normal.  It finally occurred to me that maybe this medication was causing all of my misery, so I looked up the side-effects and sure enough they are all listed. I am in the process of weaning myself off of this medication and feel like absolute crap. I wish I had never started this medication! My recommendation is: get a sleep study, try "natural"(less addicting) sleep aides, or trazadone and therapy for stress."
