i've been either falling asleep while driving...or passing out or something...i don't know what happens...i've noticed my left eye has been twitching for the last 3 or 4 months...i get a headache on the right side of my head and it goes over the top of my head....my vision gets blurry....and the next thing i know i jump and wake up or come to or whatever...but its scary...any advice? i see my neurologist next thursday...he has diagnosed me as having chronic migraine...but this pain i'm getting isnt a migraine
