I was nervous about it too. But I had a very serious flare up 2 years ago that put me in the hospital and they still had me drinking Ensure to know I was getting my nutrients after I went home.
I have been unable to find the rice shakes Heather refers to in my area. So I don't know what's in those.
I am severely lactose intolerant and Ensure doesn't bother me.
(In fact, I'm trying to get a sample for the doc to see if I have a parasite, and normally if it were to bother me I'd get terrible "D" and I've had no luck in 3 days.)
Let me know if that's what you decide to do how it works. I am glad you have found another GI doc. Let me know if you try the Citrucel Caps how they work for her. It may take a week or two to get things worked out.
I'm not feeling great, but if I can help someone else out meantime, that will make me feel better. K =)
