I too am 44 and have been a nurse for 23+ yrs. It is just this past year that I am willing to have a drink on the day I work nights. I cannot believe my loyalty and committment for 22+ years, denying myself a "glass of wine" at dinner, because I was working. Well no more. Like yourself, I know my limits am responsible and put no one at risk over a glass of wine(or two) hours before my shift. Young girls come to work Sat am reaking of booze and hungover and that is tolerated because it is the night before. Coincidently, I was at a nursing appreciation dinner and sat beside my boss. It was upscale and the wine was flowing. I had three glasses because I wasn't driving and knew I was going to now have a good snooze before my 8hr night. My boss allows the greatest incompetancies on the unit, and I would invite this argument. Anyone who thinks you put anyone at risk is clearly inexperienced. You did nothing wrong!!!!
