I know what you mean. I ate half of a half of a very well toasted (read burned) english muffin w/ cream cheese about two weeks after my first fill in December and about a minute later I thought I was going to die. I had to go stand in the restroom at work until it finally passed after about five minutes. Ugh!! It was the worst feeling ever. I'm imagining something like it must feel to have a heart attack! Pain, sweating, nausia. Haven't had an english muffin since!
