Effexor can cause weight gain in some people. It did'nt when I took it.
It sounds like your Dr might be weaning you a little too fast. Listen to you body and if you have any problems ask him to make another weaning plan for you. Remar
Thank you for your response, Remar. After reading your comment and other comments of people who have had experience with effexor ( I looked up the drug then all the posts), I know I made the right decision to hold off. I am going to speak to my oncologist who originally put me on effexor for my hot flashes 18 months ago. My PCP gave me the instructions above. I think my excessive weight gain in such a short period of time, is from being hypothyroid. I was panicking to remove anything that was attributing to that. I don't need anymore craziness added to the pot right now!
