insomnia
"In June 1999 I had a triple bypass.  My cardiologist, knowing of sleep problems with bypass patients, prescribed 100mg Trazodone at bedtime. I went to sleep within 5 minutes of lying down. After 5 or 6 years we doubled the dose. There have been a few nights when I forgot to take it and lie in bed tossing/turning until I realized what had happened. I get up and take it and am asleep within 15 or 20 min. I can't imagine life without Trazodone."
