I actually did that one time a few years ago. I felt disgusted with myself and resolved - NEVER AGAIN. Also I don't buy cheap mass produced pizza like Domino's anymore. I find boutique pizza shops. The only chain I use is MOD Pizza. They have a 6" personal size and they make it right in front of you. Also, pizza in moderation. Like the Hodge Twins say - eat whatever DA FUK! you want to eat(as long as it fits TDEE).
