"i&#039;ve slowly gone up from 100 to 150 etc to where i am now at 450 mg each night. between the dr. that originally put me on it to the newish dr. they messed up my dosage but i&#039;m back to 450mg now. during the times of the mess up, i would run out of trazodone and stay up for days on end until i finally caved and went to the local pharmacy and was buying everything that i used to take over the counter. i got zero relief...i highly recommend this medication..from being upped on the dosage for the past many many years it does make you feel groggy to begin but only lasts about a week maximum two."
