I'm still happily on the diet, after almost three years, except...I got cocky.

I was happily 100% for a while, but you know how it goes...I sort of slipped into eating occasional munch food, usually cream with fruits. It didn't affect me and was satisfying, sooo...about a month ago, I started to experiment to see how much more dairy I could get away with (and still feel/look good). Before I knew it, I was eating ice cream and sour cream, along with fruit and egg yolk, almost every day. For about two weeks, I felt fine.
Then, suddenly, I didn't feel so good: I started getting severe abdominal pain, just moments here or there. I just figured I was getting my period (though I haven't had such bad cramps in a long time). I also had a lot of gas, which I ignored. (I guess I wanted to keep on eating my cream and cheese!)
Then I started getting really sick: my throat felt constricted and I was getting headaches. My roommate had a virus and felt similiar symptoms, so I thought I had the same thing. Then, three days ago, I woke up and my right eye was completely swollen shut! I was also having trouble breathing. I was SO scared! Anyway, long story short: it turns out I was having an allergic reaction (to dairy)!
My sister is lactose intolerant, and only developed it as a teen...I'm not sure if the Wai diet made me even more sensitive (because a dairy allergy is more severe than lactose intolerance). I've been reading up on allergies, and it's striking how common dairy/wheat/soy allergies are! Does anyone know if this is connected to their bad protein/beta carbolines/opioid peptides content? It's almost as if our bodies are protesting all the bad food that we view as "healthy"/normal! (But why only in the last 20 years? Well, it doesn't seem like a coincidence that it is rising along with obesity/disease/etc....

To be honest, I am glad that I have been diagnosed as "allergic," because what better motivation for not touching the stuff again?

Anyway, my main question: 1) When will the remaining dairy leave my system? It's been three days and I still have some uncomfortable (but don't worry, not life threatening!) symptoms. I know it's two weeks to get back on track with the 100% diet, but I'd like to know when my symptoms will go away...
and also:
2) please someone tell me that I can still eat egg yolk. Because I will die without my egg yolk...I LOVE my egg yolk! Because it's RAW, so it's not allergy-causing....(try explaining that to my worried mother)

Thanks!
