So good to get an update from you, @eileenb1022. It sounds as if you are getting your appointments in place and you have lined up some good medical providers that you will have confidence in.

Yes eating small amounts is important. After three surgeries on the upper digestive tract (also had the gallbladder removed), I get the "full feeling" very quickly. It really is not all that bad once you get used to it. When eating out at a favorite restaurant I know in advance that I will be taking at least half of the meal home in a to-go container. On the bright side, there is less cooking for the next day.
