I am sold on Airborne, as directed, at the first hint, and Zicam oral spray. As a psuedo clinical study, my wife and I both caught the same cold, I did as noted, she did nothing, mine lasted, oh, 2 days of runniness, then stuffiness and coughing and she had it for 2 weeks, intense.

I'm also a firm believer in thinkin' positive- I was sure the nostrums would work, she was resigned to riding it out.

Unscientific, but there it is............
