My husband took Amytriptyline for many many years for chronic body pains from fibromyalgia. He had no bad reactions to this medication, but if he didn't take it..he would be writhing in pain.
He was first diagnosed with Epstein Barr...but that later turned into fibromyalgia. I don't remember if he ever tried Cymbalta. He did take amitriptyline twice a day..I believe the mg. was 100mg...not positive about that at this time. He passed away in 2017 from Parkinson's with Lewy body dementia....which could have masked any other symptoms like being tired and not sleeping well...this all went along with his rapid progression of his type of Parkinson's, so it's hard to tell. Whatever works for you is the only answer you need to listen to. Bless you...enjoy this day!
