I know someone who has had epilepsy since he was a young teen and has been on phenobarbitol for years. Most of the time it was controlled, but occasionally he would have a grand mal seizure and more often, petit mal seizures, particularly in the morning. However, my sister-in-law told me that in Africa where they lived for a number of years, there were many cases of epilepsy in an area that was zinc-deficient, so I suggested he start taking zinc. Since taking 25 mg of zinc (1/2 a tablet) every night, he hasn't had any trouble, except once when he was taking another brand of zinc. I don't know if I can mention the store, but the good brand was from SuperStore and the other was from an online vitamin place.
