George, you are right. I think it is the upcoming disease because someone has finally taken notice. But you are also right. I would happily go back to my yummy whole wheat/non GF oats, barley, etc. foods if I could. But, I just don't want that constant stomach ache, plus a number of other wonderful things I am happy to do without. The ulcers in my mouth are gone.
As for foods, I hope, for you who are stressing about extra carbs, that you are not using white rice. It is just as bad as white pasta. Brown rice, quinoa, GF oats if you can handle them as most of us can, beans, if you can eat them, and maybe a fiber supplement if you must (make sure it's GF.)
The bottom line is that you learn to shift the things you eat, and use the grains as a smaller part of the diet. Flax is good; make sure you start with ground meal and keep it in the fridge. You might also up your water intake. I've needed to do that, and I hate water.
Good luck! I can tell you that after 18 months, wheat, when I've cheated just a tad, doesn't taste as good as it did! I reserve most of my treat allowance for VERY, VERY dark chocolate: 85% or so.
