I have the sleeve and am 6 to 7 months out. I can eat whatever I want just smaller portions. I tend NOT to eat lots of bread or sandwiches cause it fills you too fast and you can't get your protein requirements, and its a different full feeling, like a bad one.
My main diet consists of Eggs, chicken,steak,chili, salmon, tuna steak, yogurts,cottage cheeses, nuts and salads...I have the occasional slice of pizza or 1/4 of a piece of sub sandwich, but processed coldcuts dont sit to well with me..
You basically have to see what you like to eat again and you will be eating smaller, human sized portions of it. Like now I can barely eat 2 eggs and 4 oz of Icelandic yogurt for breakfast, where my old self would eat 3 to 4 egg omelette with cheese, 2 slices of toast with PB&J and 4 slices of turkey bacon, and 3 cups of coffee and still be hungry an hour later..
The major difference is separating your liquids from solids and not drinking with your meals, you dont realize how used to it you have become.
