you will do fine. they just want to take blood, question you few things like your history, medications blah Im sure which you already had it done today
dont worry or be afraid about after waking up surgery but like many of us who went thru.. all get various feeling..
Funny thing was.. when I got my first surgery in july 2001.. I felt like I got run over by a truck, and I felt like someone punch my jaw real hard..
This time I just had 2nd surgery on right ear jan 4th.. i woke up feeling pretty good, i though that was odd, dr said its good news, I said the noise etc he said thats good news blah etc im like what the heck are they crazy or what... Few days later.. yesterday I feel like I got run over by a truck but... at same time I came down with cold! what a nasty! just don't get yourself sick, keep yourself germ-free from everyone
and be sure to keep update with all of us

I rarely post out here but I m wishing you your luck and do share
hehe
