I've been in America for 5 weeks odd now, and have been ill Mira.
I also have severe allergies, and a lot of the food (in restaurants etc) is out of the question for me. I have tried, but it's very very hard to find anything I can eat. I know it sounds ridiculous, but it is true nonetheless.
Being in hotels makes it hard to prepare food, but we do it anyway....unless I eat food I have made, it is risky.
