Yes... anti-depressants often increase depression, go figure... most have a big warning on the packets stating this as the first point. This is what pretty much removes sexual drive... and I agree, this is why physicians are just getting so lazy and blase, because its not their lives affected. Change meds if side effects aren't working for you, and make your physician work at finding the right one/s that work uniquely for you, with the least side effects.
If what you have is the least side effect, then you may need to take up a decent exercise regime, as exercise will increase the bodies natural chemicals for sexual drive.
