Is this okay Post Op?

I have my op in two days, and for two weeks I've been doing a liver shrinking diet.

Meal replacement shake for breakfast, Meal replacement shake for lunch and then chicken and vegetables for dinner, and small bit of fruit.

What did people eat the same day as their removal? I know I'm probably not going to want to eat loads but I am craving some toast and a plain digestive biscuit. I think i'll cry if I can't have some toast these two weeks have been hard.
