Jill,
Wow! You definitely haven't let MC slow you down. Good for you - that's awesome.
I can remember when you were mighty sick, but even then, you refused to let MC keep you from training and successfully competing. You're quite an inspiration.
I'm sure that the procedure in January will go well. Hospitals seem to be a bit better prepared to handle special diet needs these days, than they were a few years ago. I had surgery last February, which required a 7-day hospital stay, but they sent a nutritionist to my room to work out my menu. The first day following surgery, of course, I wasn't allowed to eat or drink anything, and the second day I was allowed liquids only, which was a bit tricky, since the only options they had were low-fat milk, or fruit juices, but I managed to survive on apple juice, and one of the nurses was kind enough to sneak me a can of Sprite. After that, since I couldn't tolerate things such as cream of wheat and oatmeal, and none of their soup was GF, the doctor decided to allow me to eat solid food, and so I had a few real food choices from then on, (mostly chicken, fish, and rice). The biggest problem seemed to be that when you tell them you have to avoid gluten, they immediately think "salads", and salads are not suitable for someone with MC, nor for someone who has just had abdominal surgery, for that matter. I tried some salad, but it didn't digest very well.

Other than that, I've been pretty much doing OK, lately - can't complain.
Being able to have someone bring you some of your own food, should really facilitate your recovery. I wasn't able to do that, because my surgery caught me by surprise, but since you will be able to prepare for your hospital stay, ahead of time, that should be a big help.
You're most welcome, of course. Please keep us updated - you're an inspiration to all of us, and especially newbies who are wondering if they will ever be able to safely leave the house, again, (let alone run a marathon).
Love,
Tex
