I know how you feel. I get really hungry, but feel full after only a few bites and food doesn't't taste all that great. I guess that's not a bad thing , but it's not what I expected.
If you are craving pizza, try cutting a chicken breasr really thin sprinkle with garlic powder and broil in the oven til it's done. Add your pizza sauce, pepperoni and mozzarella cheese and pop it back under the broiler until the cheese is bubbly. Hopefully this will satisfy your craving with less calories than the real thing.
I am 6 weeks out and trying to find my way, but it is a process. Good luck, maybe tomorrow will be better
