I'm currently on 600mg of Lithium. It's helped but not as much as I was hoping, I think my pdoc plans to increase my dosage. so far the only side effect I've had is thirstiness. But you are supposed to drink lots of water with Lithium.

I was on it previously, as a teenager, when I was diagonosed with "atypical depression" and the lithium helped with my anger, but I stopped taking it - I think because my hair started falling out. Not that it was making it fall out a lot, I was probably just trying to find a reason to get off medicine.
