does anyone know how long the withdrawal period for something like cymbalta is? the last time i took it was last thursday... i've been on 20 mg for a while, but this withdrawal is THE worst thing i've ever been through. probably even worse than the fibro itself. my rheum called and told me he didn't want me stopping cymbalta, but my GP agrees with me and told me to stop it cold turkey. my migraine is so horrible, i'm getting HORRIBLE hot flashes all throughout the day but at the same time i'm shivering all the time. i'm completely nauseated all the time, and so dizzy. anyone know how long this is supposed to last?
