"i&#039;ve been taking trazadone for insomnia since 2011.  started at 50mg but quickly went up to 200mg. after a few yrs i&#039;m down to 100mg but occasionally take 200mg. i still wake up in the middle of the night almost every night but usually go back to sleep fairly soon. but if i don&#039;t take it i&#039;ll be up for days. i have not been able to go without taking it in 4-5 yrs. i also suffer from bi polar type ii. i take effexor for that. without trazadone i&#039;d go crazy from lack of sleep, but i really would like to sleep thru the night for at least 8 hours instead of waking up after 2-4!! any other suggestions? benadryl gives me the shakes and agitation and melatonin does nothing."
