Thoreau,
Sorry you're feeling that way.
Any ideas? I ate late last evening (11 pm) some ground beef and eggs fried up in some olive oil, plus orange juice.
Sounds like a case of major food miscombining to me. Mis-combining foods can create havoc and great pain, among other things.
I found a great explanation of it here: http://cureforulcerativecolitis.com/step-1-methodology-to-eating
Maybe that you're feeling better.
