Hey Allison: that "foaming" is the same thing as "sliming"!! It's pretty gross!!

When the food got stuck, my body just produced an over abundance of mucous (must be an automatic response).

I just kept spitting it out and while I was trying to burp, the food came out...

Sorry to be so graphic. The good news is that it was not as bad as actually throwing up used to be from your stomach with all those nasty acids!!
I am convinced that my old bad habits are making this happen. I have to cut my food on my plate and then put it into my mouth. I am so accustomed to taking big bites and big swallows. It's a big adjustment.
By the way, I just noticed tonight that you had sent some personal messages. I wasn't ignoring you, I'm still learning how to navigate this site!!
I hope all is well with you and all of the other May flowers.
