"5 years on viibryd 40mg and starting to feel really bad.  i take it for general anxiety disorder with adah .  i started getting head dropping sensation at night. started beta blockers for how bad hand tremors were/are. absolute fatigue to the point of calling it lethargic from the time i wake up to the time i go to bed. every task feels like a chore, not from unwillingness but due to complete lack of strength to do so. this week the deep bone and muscle aches have started. i feel so bad and has been gradual decline over last year. just figured out the cause and i am sad to stop this medication, but i&#039;d rather have gad then this."
