I've been on 2 SSRs for a year now and haven't gained any weight.
My psychiatrist said something of interest before I began taking these meds. I asked him the typical, "Will these make me fat?" and he said, "Yes and No." He clarified that with, "Why are you going to take meds? Because you're anxious and nervous all the time. Those things often result in pacing, bouncing around the house, etc. When you're on the meds and more relaxed, however, you may expend fewer calories." Then he said that someone who is vigilant about exercise and their weight will probably remain active, thus refrain from weight gain. And in my case, he was right. I may not have as many freak fests as before, but I still take the stairs in lieu of the elevator, I park in the rear of parking lots, and I workout with Cathe 6 days a week.
In fact, when I began taking my current medications I lost weight but I was shaky and had a constant headache. He lowered the dosage and I went back to my pre-med weight and it hasn't fluctuated at all since. That was about 11 months ago.
