Lithium carb pills, at the lower end of the standard therapeutic range. There are a range of side effects, luckily for me not severe enough to impact my day to day--the most noticable one is just being thirsty all the time. We'll see if that stays true as I age, though... kidney damage is a big risk down the road.

And yup, there's some newer research about the long term benefits such as lowering alzheimer's risk, which is a nice silver lining :) My doctors have mentioned it, so probably not pseudoscience.
