I'm still waiting to be sleeved.
My doc told me that I will eventually be able to eat/drink whatever I want in moderation. He said its not a diet.. It's a lifestyle change and he doesn't want me to feel deprived.
That being said, I think it's an individual thing some people end up not being able to tolerate certain things. It may come and go. And some people decide to give up certain things because they feel those things are detrimental to their new lifestyle.
I know people who drink pop and people who eat Pasta at times. Its a very individual thing.
