Sounds like major systemic inflammation. I have had lots of food allergies and 99% of them disappeared after about 9 months of supplementing with Vitamin D3 (I took 8,000 IUs--great to start with 4-5,000 IUs and get tested to see where your blood levels are. Lots more info on the Vitamin D thread on this forum or on the Vitamin D Council's website.
If you reduce your inflammation and heal your gut lining (coconut oil is great for this), some, if not all of your allergies will likely go away. This may take some time, but in the meantime, I would definitely avoid all grains and legumes because they are just going to continue to irritate your gut lining. Also, you need to avoid the foods that make you sick or your system is going to continue to be overstressed with the inflammation and you could make yourself even more sick.
Read the recipes on the blog and check out the recipe forum for some help with the food boredom. I'm in the same boat--getting very bored with my eggs every morning!
