My coworker, Caitlin, forwarded me an article from the Consumerist.com about Zicam, saying they have settled over 400 lawsuits from users who say they no longer have a sense of taste of smell. Great!!! I mean, who really needs to taste or smell things, anyway? It's totally overrated.
I will say that I have never personally experience any of these negative side effects from the product. I've only experienced a speedy recovery and a slightly less snotty nose (TMI?) There have also been several articles refuting the claims of the non-smellers and non-tasters, but I'm too lazy to look those up. Google them yourselves if you really care that much.
I think most people are generally turned off by anything that you have to put up your nose (except maybe Lohan- oh! You're burnt!) but I think it really works for me. Only time will tell if I lose any of my senses, but let me say this: If I am unable to taste the sweet, delicious magic of McDonalds french fries there will be hell to pay. Hell!
