I currently take 100mg at nightime to sleep. Recently had back surgery and noticed if I stop the Trazodone, I feel great ( more energy, joints do not ache, back feels great ) but the side effects are terrible. Nervousness, feelings of everything closing in around me, aching joints, instability, sense of no balance. Been taking this for quite awhile 5 + years, but recently noticed these side effects in the last 6 mos. I need to get off this thing.
