bipolar disorde
"Very drowsy for the first week of taking it, but once your body gets used to it, it is a great mood stabilizer. I've been on it 6 years and it calms the edginess and irritability with bipolar. Also makes you sleep like a rock. My weight only changed when lithium was added to my meds. No significant weight gain for me. If I go a few days without it, I notice I'm on edge constantly."
