Has anyone else experienced Lithium weight gain and what do you do to reverse it or at least stop it?

Has anyone experienced Hypothyroidism -- An under active thyroid.

How often you you have to test your thyroid and check you lithium levels?

Is it possible not to gain weight on BP medication?

I understand the first few weeks is basically water retention.

I try to exercise as often as my mood allows it. I eat really healthy but binge about once in two weeks mostly red velvet cup cakes....

Oh and then there is epilim that is also apparently notorious for weight gain, what is your take on that?
