my healthy secret

I almost hate to write about how healthy I've been in fear of jinxing myself, but I feel like I should share what I consider to be my secret.  I am (or hopefully, was) the type of person who would get at least 3 good colds a year.  The type of cold where I would inevitably lose my sense of smell and taste, and there is nothing worse than losing my sense of taste; I love food too much.
The last six months or so, I have been religiously taking Emergen-C first thing every morning, and then before bed, I've been taking Homefirst's Maintenance Program for Women which includes vitamin D, a multi-vitamin, and an omega 3.  I've also added in an 'emotional well-being' supplement to chase away the blues and the blahs.  I was taking Dr. Weil's Mood Support Formula, but on my last trip to Whole Foods they didn't have it, so I found a replacement:  Gaia Herbs' Phyto-Proz Supreme (which I think I may like better). 
A couple months ago, Ignacio got pretty sick which he rarely does and I thought for sure I would get sick as well, but I didn't.  I can only credit my supplements and my dedication in taking them.
If I feel a tickle in my throat or a bit of the sniffles, I will take an extra dose of Emergen-C and and extra vitamin D.  So far, so very good.

Now I am crossing my fingers the Universe doesn't punish me by admitting that I haven't been sick in quite awhile.
