"i&#039;ve been on trazodone for more than four years. started for insomnia during my phd program. i&#039;m a woman, 5-10, 170, and work out five days/week). i need between 100-150 mg to get this medicine to work, but i have never had the hangover the next morning. most sleep aids knock me out for days - that&#039;s never been an issue with trazodone - i would not have finished my phd or survived my first year as a full-time professor without it."
