A GREAT website is this: http://www.glutenfreedrugs.com/
It is kept up by a pharmacist and lists many gluten free prescription drugs.
Truly, I would urge to you check ahead of time, and make sure you have family or friends that double check everything you are given at the hospital, drugs and food included. I had surgery just last month and had a horrible time getting gluten free pain medication. We emerged from the hospital too late for the pharmacists to contact the east coast where the drug companies were. Not ONE of the pharmacies in the entire city had the known gluten free medication of the type I needed, so it had to be ordered, but it was the weekend so it took three days before I got pain medication I needed. I would not wish that on ANYONE, truly!
re: the food. It gets easier. Slowly, but it does. I think it was easiest in the beginning when we stuck to naturally gluten free stuff, like rice, veggies, fruits, and big chunks of meat. Gluten free soy sauce helped that immensely.
Wishing you good, good luck!!
