So sick that I used one of these guys. I'd heard alot about them, and if I were any less sick I probably never would have tried one. If I weren't such a weeny about taking any medication, I would probably never have used one. But so far, so good... it was a weird sensation to be sure, but I've been able to breathe for the last 30 minutes through my nose. Which is 30 minutes longer than I've been able to breathe for my nose for the last week.
