Well, this has been a most interesting read and thank you all for posting your experiences. I have only been on this *@#$F^% Effexor for 2.5 months at 75mgs and have switched to Wellbutrin as my BP was going over the top. I have mild depression and some OCD. My god.....the brain zaps are the worst thing and until I read a posting here it happens when you shift your eyes from right to left. go ahead...try it. It has only been 2 days since I switched and I have all the symptoms talked about here except the headaches. I had those pretty much every day on effexor and went though bottles of Tylenol. I have yet to read a post from anyone that indicates how long this will last. i think I\'ll go freakin\' nuts if it goes on much longer . Good luck to everyone!
