There are many threads on this one.
Long story short: average weight loss in the clinical trials was like 5lbs. And they did the clinical trails with a bulimic group. So, maybe that had an effect?
Anyways, they generally don't seem to cause weight gain like some other meds.
As for me.......I gained something like 60lbs on them and now have lost 118lbs on them.
I think that the weight loss benefits generally come from the lifting of the depression, rather than any *magic* of the pills.
And, Congrats on starting to really deal with your issues! That is a great step! It takes so much strength to do that.....so more power to you.
