I would recommend staying away from hand sanitizer containing anti-bacterials. Since they prevent your body from being exposed to an illness, you have no shot at developing any immunity to it, and so lengthens the time your body will need to fight off that particular illness/germ in the future.
Also, while I too have experienced the mircales of Throat Coat, black tea with lemon or honey in it is cheaper, easier to find, better-tasting, and just as effective. Gargling with salt and warm water is also key--every doctor in creation recommends it! Although I have yet to try it myself, eucalyptus is also supposed to be wonderful.
But if you kiss me,
If we touch,
Warning's fair:
I don't care
Very much
