epilepsy
"I have had seizures for 40 years. I started on Dilantin and phenobarbital. I had breakthroughs with petit mal seizures, but my grand mals were controlled. When I became pregnant they stopped the phenobarbitol and started me on tegretol.  I had more seizures, petit mal and partial complex. Finally a new doctor started me on phenobarbital again with the Dilantin and Tegretol and I rarely have any seizures. When I do they are only petit mal and last only a minute or so."
