I took 400 mgs. (30 min. before bedtime) every night for a long time and I did well on that. I guess my system changed because I started having the "Trazadone hangover". I cut back to 300 mgs. and that seems to be working OK now. Tried to go to 200 mgs. but I was waking up 4 or 5 hours later. My P-doc said try 250 mgs. For me the thing about Traz is the dreams (more often nightmares). They are very vivid, weird, and complicated. I don't feel a need to stop taking it or to change to another med because of them. Guess I'm used to the dreams...I have them about 4 out of 7 nights.
