I feel the same way about QWISO. I'm very sensitive and I'm unable to use iso products at all. One, they're nasty tasting, even when it's only a faint taste. Two, I get raw throat and lungs. Just horrible stuff and that's washed and 'cleaned' iso. Washed multiple times with ethanol. Bleah

Isopropyl Alcohol, just don't do it. lol
