"i was on 150mg of trazodone for about a year and a half. my sleep was awesome. a little groggy in the morning, but i got used to that. unfortunately, after a few months of starting the med, i began having all day severe dizziness. didn&#039;t think that it could be from the trazodone and ended up seeing two neurologists trying to figure out what was happening. they couldn&#039;t find a cause. out of frustration i quit the trazodone cold turkey to see if it could be the cause. sure enough "
