Thanks Paul! The weird thing though is eats almost nothing. Some cheese, but went gluten free months and months ago. His diet is: a.m.--gatorade and Udi's gluten free bread . Lunch banana and dinner hummus and tomatoes with mozzarella. I don't even think there are enough calories in the day. But he feels the gas and bloating so much that it overrides any feelings of hunger. We are both so stumped.
I think he should start using his standing chair daily. Do others? It seems gravity might help.
