I'm currently trying to wean off effexor-xr and finding it difficult. I was on 75mg 1 tablet a day and have managed to get to 1 tablet every 2.5 days which has taken me 3 weeks to do. I feel so sick all the time. Head spins, nausea. Does anyone have any advice on the best way to wean with the least side effects and also how long is this going to take me to get completely off them?
