Pam, but OF COURSE I've had Diet Coke today!!! First thing this morning! I've had probably two servings today (so far, but the day is not over)! I've been gagging down my water otherwise. I am up for the challenge, but I'll start tomorrow. I actually may TRY not to have anymore today, but I still have what's left of a 2-liter bottle! It's calling me, begging me.....
