when i was ill i found it hard at first but really if you read packets of the food you buy youll find that you can still have some of your favs!!
liks dons ham, if you read bottom right hand corner, their ham and hot dogs are gluten free. and my mum has put me onto these little chocolate puddings that are gf, i can eat wheat again but istill eat them!!!
good luck, but be careful witht he gf bread some is noce, but you generally have to freeze it and thaw when you want to eat it - thats what i had the most issues with, but you can get flavoured corn cakes to have sandwiches in.
oh, and check out muffin break, they do fantastic sweet and savoury gf muffins!!!
i dont know if it wil effect you, but white sugar makes soem coeliac ppl sick, so maybe go onto raw!! and remamber to get all your vitamins!!!
