Lent: 40 Days of Diet Coke-less-ness

I've never given up anything for Lent. My faith tradition does not require that. This year I've decided to exercise some self-discipline and give up Diet Coke for 40 days. To most people this may seem like a little thing but I'm going to miss it. I won't be switching brands either. The plan is to go soda free for the Season of Lent. Wish me luck. Are you giving up anything for Lent? Want to tell me about it?
