I take Lamictal 150 mg twice a day. I have have to increase the dose due to the additional stress of college, but I was stable when I was working at a job I like. I also had to add and anti-depressant and a stimulant for the same reason. I am taking 500 mg of Epival/Depakote for migraines specifically, though it is also a mood stabilizer. As for it being wieght neutral, I don't known, my metabolism has slowed, but I am in my late 20s and it's common for most people's metabolism to slow.
