I was taking Effexor XR for chronic migraines and I stopped it a week ago after tapering from 225 to 150 and then to 75. I was taking 75mg for around a month and a half and am now trying to stop taking it but I'm having withdrawals (Dizziness, hot/cold, headache, shaking/jittery, brain zaps). Is there anything else i can take to stop some of these effects, and how long will everything last?
