Well, vitamin C has been proven to help ward off colds and vitamin E is great for the skin so I don't know what tests the poster is referring to.
But the problem with this one is that you can't get any rest because when you lie down, your lungs fill up and you choke....yeah, I'm taking robitussin and it helps, but not a lot. Same as when it was in my sinus', I was taking coldaside but didn't seem to help.
This one starts in the sinus', then moves to the throat, and then into the chest (like many) but to me, it hit 10x harder than any I've had before.
As for CG et al and not getting colds....F you royally ya bastrich lol.... I know more than a couple people like you guys and you bug me to no end.....just as bad are the ones who get colds very easily, yet it doesn't affect them much and they get over them quickly. I used to date this girl who would catch a cold if she was in the same room with someone, heck, if she saw someone on TV with a cold she'd catch it. Yeah, and her idea of a bad cold is one sneeze, once a day. She'd give it to me and I'd be on my ass for a week.......
