I was lucky and had a good GI doctor who referred me to nutrition and I now also use an app on my phone called the gluten free scanner.
Life is certainly not easy, I don't eat out and most times we have to prepare two meals in my house... sadly I don't know where in my fam the celuac came from.... my grandmother has no want in being tested...
This year has been a very trying year for me. In October 2015 a blood lab was done that had shown me as Celiac positive.... due to having no gastrointestinal issues at the time it was told maybe it was a false positive to go about my life, unless symptoms showed.
then the weekend before Easter 2016 I went to NYC for a show and after a 3 hour drive home...
The way my GI doctor explained too me was that it depends on how advanced your Celiac is. For example some people can tolerate a small amount of gluten and so it would take longer to have any effects.
but someone whose advanced and cannot tolerate any gluten, not even traces (me for example) I can't go out to eat because even something that says gluten...
