Phenobarbital
"Had epilepsy since 14 now way over 60 and been on phenobarbitone all my 
life.    Doctors have tried new ones on me but they had side effects whereas
Phenobarbitone have been good for me.  
Epanutin caused gums shrinking and were bad for my liver.  
Now been put on Keppra and I cannot keep awake and ear hurts. Docs leave my pills alone please."
