Taking Viagra the Week Before Revision Rhinoplasty, Should I Postpone Surgery?

Seven months after my first surgery, my surgeon wants to refine the tip. However, 6 days before surgery I drank too much and lost a bet and took a Viagra pill (I know stupid) I am just wondering if I should postpone my surgery or will taking that pill not affect the healing? This is a serious question not a joke. I dont need a lecture on taking the pill, that was a stupid act on my part....just worried is all.
