My wife had Hyperemesis Gravidarum (extreme morning sickness) with both pregnancies. If untreated, it CAN KILL you......anyway.....she got tired of having the smell and taste of vomit in her mouth so she asked me for the 'Listerine' get the taste out of her mouth. By this point she had vomited into all of our 'basins' (6) so the last one still had vomit in it. As she was still 'sick' and throwing up, she had no choice but to keep the basin under her face. Well she took one 'swig' of the mouthwash, swished it around her mouth and spit it into the basin. The basin had about 1 inch of vomit in it. It was absolutely amazing.....one small mouthfull of 'Listerine' COMPLETELY Neutralized the smell. A small amount into the other buckets completely cleared all the odor.
Ever since then I carry a bottle on my bus (ambulance). I've even poured it onto patients and it completely cleared all the odor. It is fantastic!!!!!!
FYI Listerine is in ' ' marks as it is not the name brand we used.....it was the Walmart generic of Listerine. It works exactly the same.
