I too have serious, life threatening food allergies, and have dealt with them for decades. I canot be in the same room with any kind of seafood (fish or shellfish). This sadly means that I can rarely go to resterauntts because of cross contamination.
I am able to manage everything pretty well by reading lables on foods and being strategic when I grocery shop. You know, I did find it overwhelming at first, but I found the best way todeal with it was to breakeverything down and deal with the information one peice at a time. Here are a few websites that can help:
www.foodallergy.com This will provide information on food allergies.
www.epipen.com This will provide information on epipens.
www.medicalert.org This has information about medic alert bracelets, should you decide to go that route. I wear one.
Just remember, you CAN handle this and so can you son.!
Oh yes, you do want more than one epi pen---one to be with your son, one tht stays at one, one in yours, etc., just in case. I have three...purse, kitchen and car.
Please feel free to pm me if I can answer any questions.
