your son may possibly be suffering from the effects of a little known condition called pds or pyrodoxine (vitamin b6) dependency/deficency syndrome which one can either be born with or develop later in life, like diabetes. my own personal seizure cure consists of taking one high potency b with c vitamin tablet daily, along with a complete multivitamin tablet every other day for added insurance against other deficiencys. you can find information on pds on the internet, or in some medical reference books. i found this information at the mayo clinics website several years ago. take care doctor b wise
