Lent and Pizza

I always give up something for Lent each year, over the years it's been soda, a specific kind of fruit snack in which I used to indulge, pedicures, etc. This year I decided to make it really difficult and give up pizza. It's only been a week and a day, but I can't take it anymore..I crave pizza...i dream about it, I envision it, I must have it. Trying to stay strong, but not sure it's going to work.
