Has anyone had Lithium effectively treat ultra rapid cycling? I think I read somewhere it wasn't great for that, but I'm curious about personal experiences.

It didn't really work well for me, I had to get it to 1500 mg before I just barely reached a therapeutic dose, and this was back when I actually took my meds regularly. I had months between a new pdoc appointment after my old one left, and I took myself off it in the meantime - I know, not good. I just thought that was an awfully high dose, but maybe others take it at that level.

To the OP, whether it helps you or not, you'll never know until you actually take it and see. Remember it does help a lot of people, you could be one of them.
