Great question. After surgery they had me at 3000mg/day and said I would be taking it for the rest of my life. After a year we started to decrease my dosage. It takes awhile to go lower, about 8weeks at 250mg per drop. If I remember correctly it takes about 4 weeks to be out of your system. Then you have to stay free of seizures. It takes time to find the right dosage level you can tolerate, a total withdrawal 1-2-3 just because you think you can, is not a safe way. Your body doesn't work that way. Everyone is different and if you are lucky maybe you can get completely off, time will tell. Listen to your Dr. Your second question, yes. Fine with me, I don't have seizures anymore.
