Hi,
Sounds like an asthma thing to me. Try posting in the Asthma forum.
HI...I am not sure it is related to ur gerd issues, but would try to use a scarf to cover ur mouth to see if by doing so if it helps.
I am not sure but there r some that can be allergic to the cold....see ur dr and ask about this...and please update us here on what u find out.
