Wow. That is a tremendous rate of weight gain. I gained about 3-4 lbs a year over several years. Slow and insidious, and without changing what I ate. Or rather, I ate less once the weight gain started and kept working out. I was only taking about 2 mg, and it was very effective for depression and anxiety. I've recently stopped it because I am now on something else that appears to be working for depression, and I'm waiting out the next few weeks to see if I relapse. It am hoping the weight I gained will come off, but it's too soon to know since I only stopped within the last week and a half.
