Ouch, i know how scary that must have been for hubby Bob. Four tablets was all i had and bang it hurt like hell all around top chest area on trying to take a deep breath. I remember clearly, at the time the thought of living like that for the rest of my life was scary as hell. And when the breathing came back, for what it is, there was a relief maybe not ever felt before. Thanks for all the lip stuff info, thank goodness i don't have any of that problem at present. Good luck with it.
