my name is Donna and I am 83years old. I took Cymbalta for fibermyolgia for years and when my perscripsstion didn t come I stopped taking it. That was 2 weeks ago and I have been sick, nauseated, vomiting, weak, no energy, crying a lot, ( over nothing) and I could go on and on. I ve been to my dr. and she was alarmed that I quit and wanted me to go on it again so she could wean me off but I refused to go on it again. My question is how long will I feel so bad?? And I m not causing anything permament , am I?
