Last year, 2011, I was cold free for the first time in my life, every year without fail I would get at least one cold, and I get them full on, they last about 4 wks, and I am pretty sick. I have used Melagel the same as you use vicks, and I spray my pillow with Sol-u -mel.
I have been in Melaleuca for six years, and am now starting to get the best out of Melaleuca due to buying the Melaleuca wellness guide.
