I did the same thing. I had to piss and that damn doctor wasn't keeping me in bed for a second! 
I didn't get to go to the bathroom for almost a week.
Don't I know it! When they "installed" the 6 screws I'm sportin' around now, it was damn near 3 frikkin' weeks before they'd let me up!
My last surgery I woke up in the recovery room and asked the nurses for a vodka martini.
Question is, did they give ya one? I got a Bud Light/day last time! It wasn't scotch, but at least it was somethin' besides 7up, or that nasty water!
