Which means going back on gluten from now til then, for maximum gut damage.
No, really, this is what they want. Because if I'm gluten-free, my gut is healing, and the biopsy will show healthy or less-damaged tissue, which doesn't prove a thing.
I have mixed feelings about this. I feel better sans gluten. On the other hand, I want to know for certain - because if this is just a gluten insensitivity and not celiac, I may not always have to be so rigidly non-glutened, plus yay less risk of cancer. On the gripping hand, tortellini.
...I miss tortellini.
But yeah. Yay bread! but boo making myself sick.
Related: will need a ride home from the hospital that morning, as I will be loopy from twilight sedation.
EDIT: The timing is pretty perfect, as it means I won't have to starve myself over the holidays - Christmas gets spent in a tiny town in North Florida, and the nearest GF resources I can find are about an hour away.
