Sacrifice

I am not part of a religion that practices lent but because I am nosey at best, I like to find out what others give up for self-denial. Most people I know give up some type of alcohol consumption. Good thing my religion doesn't practice lent, but if it did and I were a practicing "lenter" I'd give up one the following:

Work
Rocket Science
Double-flushing
Tea & crumpets

What are you giving up?
