Careful....
Read labels, and DON't eat out. If you simply say 'don't put nuts in my food', that isn't going to help. Alot of sauces and seasonings have peanut butter or peanut oil in them for flavor or even as a thickening agent. Nut allergy is easy if you read labels, everytime, and stay away from restaurants (for the most part). There are restaurants out there that can accomodate your allergy- I would call first. Google 'anaphalaxis network' and look it up. They have tips for your situation. Also, research peanut ingredient names, it is not always peanut or nut based names. Keep 2 epi-pens with you at all times and research! That is your best tool.
