Im gunna go with the epilpsy thing. IDK, the smart thing would be to talk to your doctor about it, but maybe it's not the weed. Are you on any other medications, anti-depressants or something? If so, I'd read up on the side effects and whatnot for them. Good luck man, and I for one hope that it isn't the weed, because I know what it would be like for me if I had to stop smoking because of something like that ... Keep us posted.
