Yea, since going on birth control I do a lot better. I consider it part of my mood stabilizers but! I can still have mood swings because of it. There was a few months where I'd switch with every period. I'd be kinda manic for a month, then depressed for a month, then up again!

Now, I feel more prone to hypomania and my period might sometimes have to do with that though it rarely effects my mood in a major way! My lamictal levels get higher that week off the pill so, maybe there's that too!
