insomnia
"After having an accident at work a few years ago I wasn't falling asleep until the sun came up because of chronic pain.  My muscle relaxers and pain medicines were no longer giving me enough relief to sleep at night so my doctor put me on Ambien CR.  After about 2 weeks I had to stop taking it because I was hallucinating, I was suffering from severe anxiety, I had tremors, I don't have enough room here to list everything.  I am now on Restoril and I don't have any side effects at all."
