I had a Diet Coke addiction for about 10 years. I kicked the habit this past February. It was bad at first... Like, I used to smoke (ugh, yeah...) and giving that up was 20 times easier than giving up Diet Coke. I'm finally over it and don't crave it anymore, but I'm certainly not going to go test it out. Lol.
So I don't really have a vice anymore. I do like a square of dark chocolate once a day. And there are definitely things I won't have in my house cause I know I'll scarf them all down (Pringles for some reason, most chips, cookies, brownies, ok really any junk food. I don't buy it cause, well, I live by myself and no one else is going to eat it).
Oh, SO and I are on an ice cream kick. We only spend weekends together and we always have ice cream on hand. Jeni's and Graeters mostly.
