I've been off and on Diet Coke now for the past couple of years. I know it's bad for me, blah, blah, blah and so I've determined to quit it several times. I usually am fine - I mean other than the withdrawal headaches and stuff :), until I go to a restaurant or have to run to the 7-eleven for something. Then my resolve weakens and I just have to have one! Seriously, what else am I supposed to drink when I get that huge hot dog at Costco? Obviously, I don't want to drink my calories - I enjoy eating them way too much! And nothing can compare to that fizziness at the back of your throat when you're drinking one - ahhhh, I can almost taste it now!
