Certain medication and weight loss, what so others do?

Hi there, I'm a long time lurker but am lurking no longer. :)

I'm interested to hear about other people's success at losing and managing their weight on certain meds.

I started taking carbamazepine earlier this year and gained about 12 lbs. I have been dieting and doing Jillian Michaels DVDs like a crazed woman. Had no joy until yesterday when I seemed to suddenly drop 7lbs. :-S

Other anticonvulsants meds like SSRIs can cause weight gain. They can make you hungry all the time and they just seem to make it really hard to lose weight.

I'm quite disheartened, because I worked so hard to lose weight and feel like I'm back at square one again. I was an avid Jillian fan, but couldn't do much of anything when I started these new meds. They made me feel weak and tired, but that's passed now, fortunately.

How do other people on meds deal with it?
