I was on Lithium for awhile. But for some reason my body was hanging on to it so the amount in my system was more around the toxic amount so had to stop it. Plus it made me twitch a lot. That and it just honestly wasn't making me feel so great. It did help though... But not worth it. Plus I hated all the blood tests. But I have talked to people who are completely fine on it and hardly have any side effects.
