Me too, dude.
you cannot drink bud light, unless your condition is mild.
I went through two years of eating shit, so here's some good brands:
the best pasta is made by Tinkyada, find it at Whole Foods.
the best bread will be homemade, so get a bread machine, and Pamela's is the best, buy online.
the best cookie is homemade from cookie dough mix, 365 is the brand, at Whole Foods.
pizza is iffy everywhere, there are no really good homemade brands, and restaurants are varied, I found amazing places where I live in Colorado, but can't help you much.
Look at the bright side, it makes you a LOT healthier, although you're kind of FORCED to be. Good Luck.
