I was on a maximum of 900 mg's a day and my last dosage was at 300 mg's a day. Lithium was great for me in the winter when my depression is at it's worst. As soon as the weather started changing though, I began gaining weight (water) and had horrible acne. I felt really drugged and was getting depressed from the Lithium. Every time that I would try to go off of it, I would relapse into my cycle (one time mania the next depression). My doctor finally prescribed me Geodon to get off of it and I've been off of Lithium for over a month now. My face has finally cleared up and the weight is coming off. We have decided to try something else this winter for my depression. Be very careful when you try to go off of it and always have a back up plan with your pdoc.
