I realize that antipsychotics are not "officially" called moodstabilizers, but they can act as moodstabilizers, so I wouldn't exclude them for that purpose. For example, some antipsychotics, like Seroquel or Latuda, are quite helpful for both quelling and preventing both depression and hypo/mania. Seroquel can also be helpful for quelling and preventing anxiety.

If you're interested in "official" moodstabilizers, generally meaning Lithium or an anticonvulsant, there are many options. From what I've read and experienced, some are better for hypo/manic or depressed symptoms than both, though all are supposedly good for many people as prophylactic medications. Lamictal tends to be known for its antidepressant uses. Lithium is known for both, but not as much mixed episodes. Depakote and Tegretol tend to be mostly antimanics. Tegretol, in my view is also good for mixed manias. There are other anticonvulsants that are not as first-line as the ones I mentioned, but for some they are helpful, but not all.

In my case, all of the "official" moodstabilizers were weight friendly for me, except Depakote. The only bipolar medications that were weight unfriendly were some (not all) of the antipsychotics.

You know that we are all different and react differently to meds. Your doc should hopefully suggest the best possible fits for you. What to one person is a very high dose or low dose is not to another. For example, I cannot take more than 100 mg of Lamictal without getting hypomanic/manic. So for me, 100 mg of Lamictal is the highest dose I can take. Lamictal is great for curbing my depression, but useless at preventing or quelling my hypomania, and definitely not mania. Others, find it great for everything. Actually, Lamictal is activating for me, meaning that I think it actually causes me to have hypomania/mania. I have to take antipsychotics with it. Though my Tegretol XR has some significant place in my cocktail, I have always taken an antipsychotic. Whenever my moods fluctuate (up or down), it is my antipsychotic that is manipulated, not either of my "official" moodstabilizers.
