Starting tomorrow, for the next 40 days of Lent, I am giving up Diet Coke. I'm having palpitations today knowing that this is my last day for quite awhile. No more stops at McDonalds in the morning on my way to work for the best Diet Coke soda drink. No more mid afternoon visits to the vending machine for a Diet Coke pick-me-up. Nope. All gone for the next 40 days.
