I can't sleep...really sucks...my Dad's having surgery on his head tomorrow AM @ 7:30 and I'm meeting him & my sister who's driving him to the hospital @ 5 AM.  I attempted to sleep @ 10:30 & now it's 1:00 & I haven't slept....I can't say I really feel anxious, even though he's having a tumor removed from the top of his head.  We don't know if it's benign or malignant but since you can literally touch it w/ your fingers (it's poking through the top of his skull) & it doesn't hurt him to touch it....in the MRI it looks like it's about the size of a golf ball - which isn't really that big but relative to the size of his head, it's kinda large....It's called a manengioma (sp?) and isn't really in his brain - it's just pushing down on it - so it's below his skull and pushing on his brain....anyway, it doesn't look like I'm gonna sleep at all tonight....I don't really care, as long as my Dad's surgery goes ok....I'll post it either way.....oh yeah, he's elected to have his head shaved so he'll look like Mr. Clean for a little while...
