I have serious panic disorder and generalized anxiety. I recently was told to ween myself off of Wellbutrin and begin taking Effexor - I have weened myself off Wellbutrin and am going to start taking Effexor but I get so scared when it comes to taking new medications I tend to freak myself. Is Effexor genuinely safe? Does it work? I know everyone reacts differently but I could really use some reassurance...
