My best friend has recently been diagnosed with it, and initially had a very stict diet (no meat, no poultry, no fish, even some vegetables were on the blacklist)... As her organism recovered most of those restrictions were relaxed and she's been only on gluten free diet since.
As the prices of GF product are exhorbitant in my country, it's been a great help to her that state-run health care provides celiac disease patients with certain amounts of two types of GF flour on monthly basis. She says those quantities are about sufficient.
Hang in there. 👍
