I agree your question will be better answered in the disabilities section of the forum.
Also the chefs are fabulous at coming out to the table when there is a diet restriction of some kind. They talk to you about what you can and can't have, they suggest things, discuss your likes and dislikes...etc.
Pretty sure you have to note that on your ressie though, so they know ahead of time to prepare. But the disabilites experts will have more concrete advice for you.
Enjoy your trip!!!
