I am starting to get worried hearing about all these people on liquids for so long. I was only instructed to do liquids for the day after surgery. The day after that I started pureed foods. I am supposed to do that for 2 weeks and then introduce "soft foods" for the next two weeks. I was banded on March 25 and, thank God, have had no ill effects to date. I was eating yogurt, cottage cheese, tuna, and scrambled eggs the first week!
The post-op diet is clearly an individual thing with an approach that varies from doctor to doctor and from patient to patient. Like everyone else is saying, ask your doctor first, but in the end, you should have a program that you will be able to do comfortably. Good luck.
