I am thrilled that I found this thread. I have laughed all the way through it.
I had this happen to me for the first time this morning. I didn't know if I should call 911. It lasted about 30 minutes. I hope to have learned my lesson and will chew, chew, chew from now on. The excess gas has been a problem also. My boyfriend just laughs - although we have been together for 14 years, I don't think I burped or the other in front of him. Yeah, I know - I'm a little weird about those things.
Here's to smaller bites!
