My weight gain / loss is relatively pendent on the ratio of mania to antipsychotics.

When I'm flying high in Mania Land, my antipsychotics increase. However, I don't necessarily put on that much weight when dwelling in Mania Land because I'm too busy running around doing nothing.

As I'm plateuing down from Mania Land heading towards Stabilityville, there's a cross over with my reduced energy levels and antipsychotics, that can make me typically put on a few kgs.

Once I'm stable, my antipsychotics basically taper right off (my pdoc's goal is always mood stabiliser only once I'm stable) ... and that basically drops off the remaining kgs I might have put on hitch hiking the ride to Stabilityville.

Hope this makes sense

PS: I have intentionally left exercise out of my response, simply because I'm too erratic when it comes to any form of commitment, including exercise, and usually when I'm hypo I'll be running around like a mad hen anyway burning excess kilos.
