So I've been on Prozac for the past few weeks until earlier this Monday, when I switched to Wellbutrin XL generic 150mg. I have had horrible reactions, crying panic attacks and always jittery, and I have heard that many people have had problems with the generic problem of Wellbutrin XL. It is now Friday (I stopped taking the medicine Thursday) and I was wondering how long these chemical symptoms would last. I am on klonopin from my psychiatrist for the next few days to try and get through the horrible panic, as well as I'm going to start celexa in a few days
