cluster headaches
"My GP thinks the symptoms of what I thought was Parkinson's is in fact side-effects of Lithium. I take 1200 mg of lithium daily. I gave it a low score for the side-effects, the shakes and poor balance. It's very effective in preventing clusters. I took a chance this fall and quit all my medicines. The day after I did this I got slammed by clusters. Clusters are too painful to live with so it's better to live with lithium and its side effects than with the pain of cluster headaches."
