insomnia
"I've been on 20 mg of amitriptyline at bedtime for insomnia for 6 years now.  I had been on valium after a bout with acute stress disorder, but found it highly addictive and found myself going to my shrink not for therapy, but just to get my RX renewed.  I knew then that I had to get off the valium.  My GP suggested the amitriptyline, and it is great.  No side effects, and it LETS me sleep, it doesn't MAKE me sleep.  It also lets me get back to sleep if I have to get up at night to use the bathroom.  My doc told me to start with 10 mg and move up by 10 mg increments until I found a dose that worked but that didn't leave me hung over the next day.  10 mg worked.  30 mg put me in a fog til noon the next day.  20 mg has been perfect!"
