I was on venlafaxine 225 mg/day and dropped over 14 lb in weight over a year.

I have a problem with ambition. Indecisive and forgetful. Been on 75mg for a yr. It helps with anxiety but depression I still have ups and downs every month.

I am also on 300mg Effexor and have slowly gained weight over the years, but I was also diagnosed with Hypothyroidism a few years ago which can also cause weight gain---I had no idea I had it. Worth the check.

I am on 300mg and have gained weight, i have been told its nothing to do with effexor but i know a few people in the same boat.
