Hugs to both of you. I'm sorry I haven't had the energy to get over to visit her, but the garage absolutely needed reorganizing and there was no energy left after that.

When I mourned the loss of my last protein shake, I was told about Mediclear, which is not the least bit tasty, but it's gluten free and nutritious, and it is actually calming for my intestines (though that doesn't mean anything for hers).

If you happen to get some and she doesn't like it, I'll buy it off you, because I will eventually use it. I buy it from here. It's specifically designed for people with food allergies, though it's not as complete a solution as something like Ensure. I usually make it with unsweetened soy milk rather than water.
