Your doctor can give you medication to overcome the sexual problem, plus he/she can tell you which ones don't cause weight gain. I have been on them all, and it wasn't until I took a close look at my diet and exercise, did I stop blaming the drugs. I've lost 45lbs. since January, and I always thought I ate healthy, and I've always walked 3-5miles a day. But in reality is was a couple of bad eating habits causing the weight gain. Also, any weight gain on AD's is minimal. There are no drug replacements for depression. We all have had to switch our meds, but once we found one that worked, it was well worth it.
