Glad to hear the h202 in the ears helped you Rog. My wife thinks I'm nuts, but I'm now putting a few drops of it in each ear whenever I feel the slightest bit off. The bubbling sound does give you the sense it's working. I did catch 1 big cold where the drops didn't beat it, but I probably should've re-applied drops every 30-60 minutes & started much sooner. Once a cold sets in, you almost always have to tough it out.
