I don't honestly feel like I'm forbidding my best food, although I do miss just being able to eat anything while out. We make some of the things I like at home without the problem ingredients, for example chips. I can also use honey in baking. I've never been fond of very sweet things anyway, so that helps. I also enjoy home cooking over fast food.
Reading the ingredients on something appealing and seeing "dextrose" on them will immediately put me off it now as well. I just think of the migraines and see it as a "migraine in a packet" 😆
