Still going strong! Cravings seem to have gone altogether, I'm still eating well and walking 3 miles a day to and from work.

I managed to go all of yesterday without diet coke. Today, not so much. I was up all night with withdrawal symptoms, aka the worst headache ever. By lunchtime today, I decided enough was enough, and gave into a bottle of diet coke. It's never hindered me before, and I'm still getting my water in regardless, so I'll see how it goes. If I slow down too much or stall altogether, I'll try giving it up again.
