Lol thank you so much for this thread because for the longest I've wondering what PB meant and now I know. Well today was the first time that I experienced the foam and I can't believe the pain I had in my chest, I guess I just forgot to chew more carefully. I thought to myself what is happening to me and where is this all coming from.....I had tears in my eyes make up was running down my face. Trust me it wasn't a pretty site so needless to say I don't ever want to experience that again. :tt1:
