I started seeing a dietician and went low carb (did it with hubby), as for pills...

Lithium

Zyprexa (was daily, switched to as needed for sleep, big weight gain pill for me when it was daily) - this was the big change that started it I think. This pill was the devil for me, haha.

Oxazepam
Lamictal
Seroquel

And metformin - This was also a big thing for me, it helps weight loss in non-diabetics, but it also forced me to wean off of fried things (doesn't work well for me with that pill.... ....)

And when I started losing weight, my mood improved and then it sort of got me into this new thing of not liking being in the house.

I joined a gym too, but that's only for cardio to help my mood. It has an effect, sure, but I pretty much do it when I can't go and walk somewhere.
