I am in my 4th day of duloxetine withdrawal. I am having strong flu like symptons, very bad stomach cramps, nausea, dizziness, crying, confusion, terror. It really hurts. I am doing this for my partner as we are hoping that coming off duloxetine will help prevent my frequent and dangreous bouts of mania. How long will this pain last? What happens after withdrawal? Does anyone else have any experience?
