A while ago a couple of my daughters were reporting symptoms to me after eating eggs. So I thought about this a bit, and decided to try sourcing better quality eggs and eat them exclusively, just to test. The kids said eggs were well-tolerated again, and no more egg ickies. We also discovered how good better eggs taste - might be a duh! moment, but sometimes you just have to experience things yourself to get convinced.
It might be an idea. Glad you are feeling better, though!
I have a mantra that I have spouted for years... "If I eat right, I feel right. If I feel right, I exercise right. If I exercise right, I think right. If I think right, I eat right..." Phil-SC
