I am on 600mg of Lithium right now. I have lab work on Monday for them to check my lithium levels. Then I have to go see them again on Tuesday. As for my symptoms. I have feelings of self-doubt. I'm sitting watching a movie and all of the sudden this heavy sadness feeling comes down on me. Some days I feel sad and then others I feel fine. I have started fights with my mom. Then I have days where I don't mind being with people. Others, then I could care less. I have a symptom that I'd rather not mention on here. I don't want to get myself kicked off.
