seizures
"I had my first seizure February 2014 and was prescribed Keppra. I took it for a while and experienced all the symptoms as everyone else: depression, fatigue, mood swings, hallucinations, etc. You name it I had it. I had no energy and all I could do was sleep. I got tired of living like that and one day decided to stop taking them, bad move. It was fine for 4 days, I was energized and happy but on that day I had another seizure. I told my doctor and he changed my prescription to Trileptal. I have been on it since that day and the only side effect I think I have would be hair thinning."
