Dee- Yeah, I'm wary of the mind games- I'm quite the genius at playing those with myself too!
It may seem seriously stupid, but I hate to waste stuff, and not eating/throwing out things because they contain miniscule amounts of alcohol (or, in the case of the mouthwash, that I don't swallow) bothers me perhaps more than it should. I don't intend to buy any more products containing alcohol, though.
