I have had to give up my guilty pleasures when it comes to food. Salami, pepperoni, hamburger, ice cream, pasta, soda, so many more. Funny thing is rarely have cravings now. I mostly follow the diabetic diet and actually enjoy it.
I don't really have one, but my wife insists on ordering crab rangoons from the chinese place up the street any time we go there. She doesn't even ask for them anymore, I just know to get them by default, lol.
