I was on lamatical for a short time. ended up with a rash across my chest. I don't remember it. ended up with flu like symptoms took tylenol for severe headaches and ended up with acute liver failure. 2 weeks missing last year. was off meds for a year, went back to pdoc due to symptoms of mania returning, tried lamatical ended up with flu like symptoms and severe headache from 25 mg. only took that one dose, scared the hell out of me after what happened a year before. am on 300mg lithium, but when doc tried to increase to 600mg I had painful side effects. 300 seems ok, but things don;'t seem any different.
