Right now I am taking pexeva. When I try to discontinue taking it under the advice of my doc. I have bad reaction from trying to get off the stuff. How long does it take to get out of your system. They wanted me to try Bupropn HCL (Wellbutrin), but I would like to get off all this stuff. Was taking because of the lost of my father and all the stress. But that has been awhile and I want off. But having a hard time. Any suggestions would be helpful.
