I was on 150 MG a day for 6 years before Effexor stopped helping my depression. I tried to cold turkey but lasted one day before going back. Then I tried to taper off but that didn\'t work either so I started taking Wellbutrin for a month and then I cold turkeyed Effexor. That was 4 days ago and I still experience mild dizziness, a sore neck and feeling like my head is floating. I believe that exercise, vitamins and just forcing myself to keep going have kept my symtoms mild. But it has been only 4 days, so we shall see. Good Luck
