I hope you find the answer sooner versus later! Even if it means telling those doctors whats what LOLLet me tell ya, if you felt like I did after that one bite (I didn't even swallow the whole thing. Spit most of it back out.) you'd not want another. I was surprised at just how bad it was and how quickly things went south.
I've had bacon. That didn't bother me, but then I've also noticed that I can eat some things occasionally and they don't bother me but if I eat them more than once a week or so I start having trouble. It's been an interesting journey so far -- but I don't care. Whatever I have to do to get to feeling better. And I do mean whatever.
