I started 50mg/day of Trazodone for sleep issues . 3 days in and I'm MISERABLE. I can hardly stay 3 days in and I can hardly stay awake morning to night... My body is weak I have no stamina at the gym (I'm a fitness trainer and I am accustomed to pushing limits) my head THROBS terribly from morning to night. Are these symptoms going to fade and my body will adapt... OR... are these serious and I need to stop taking?
