This has been a lifesaver for me for years. I am constantly amazed that no one I tells has heard of this. My husband was recently in the hospital for 35 days (!) and not one nurse I told had heard it (though I learned it from a nurse, in the same hospital, years earlier.) This REALLY works. Even in mid-lurch, starting-to-wretch -- I keep those little tear-open alcohol wipe packs in my purse..
