"i&#039;ve been using trazodone at 50 mg for anxiety related insomnia. i would try to sleep but i could not get my brain to shut off. it took effect within a week and i have been taking it for 20 years. my doctor is finally taking me off of it.  before trazadone, sleep was hard to achieve.  while i was on it, i got my 6 - 8 hours of sleep and woke up refreshed and ready for my coffee (only one a day)."
