So, I had been feeling really crummy for a few weeks and could not identify a source of gluten. I thought maybe cross-contamination but if that was the case it would have to be persistent because my symptoms were not getting better. I went so far as to inquire about the vodka used for a vodka sauce I had twice during my reaction period. Then today for lunch I went to a place I frequent with an excellent gluten free menu. They even bring out special "gluten free" chips to serve while the rest of the table has bread. Only this time the waitress was informed enough to let me know that they do not use a dedicated fryer for the chips and so if I'm highly sensative I may want to beware. I think this may have been the cause? I've eaten there several times and eaten the chips without thinking to ask about the fryer. Needless to say, I did not partake in the chips this time around.
I think sometimes it just feels good to come up with a potential source of the problem.
