I was taken off my EffexorXR 225MG. And was prescribed Wellbutrim150MG. I have the shakes. I feel confused. Now, and then I get these shocks in my head. My first week I could not sleep. I was so anxious. Im going on my second week. Oh and by the way I was not weened off my EffexorXR. My doctor does not want me to mix my meds. How much longer before I get to feeling better? I also did not notice until I read my Medicine bottle that I was issued generic. I am requesting from my doctor a.s.a.p. I want brand until I get adjusted. Then I be glad to go back to generic. Has anyone been in my sistuation? If so let me know how long it took to getting adjusted to Wellbutrim?
