"because of depression  i had developed insomnia. my doctor had prescribed me ambien, but that wore off real quick that it wasn&#039;t working anymore. then i was feeling even more depressed because i was worrying about sleeplessness which led me to a viscious cycle, then i tried this trazadone , it has been a god send for me. i feel normal again i sleep like a baby, at first, before trazadone i was sleeping about 3 hours or so. i have 50 mg and 100. i usually go with 50 and i&#039;m a pretty big dude 250lbs. just take it with a lil food before bed time,if u don&#039;t it won&#039;t work as well. good luck and be patient if your new to this drug. you have to do a lil experiment on yourself with this before u get it right as far as in dosage and time."
