"i take 600mg lithium the only side effect i have are the tremors. have been on it for the past year thought i was taking it for 5 years when i was first diagnosed with bipolar 13 years ago. i wanted off it then because i was doing well and i continued to do so for many years afterward until the depression came back. then after trying different meds that were unsuccessful i went back on lithium. i&#039;m amazed at some of the very high doses some are taking as mine was increased to 800mg i wasn&#039;t even on that dosage a week and had to reduce back to 600mg again as i went toxic. i remember depakote causing my hair to fall out and it was an extremely good med other than that."
