I mentioned this briefly in one of my threads from 2 years ago. I truly couldn't live without this stuff. If it's just a placebo, it's a darn good one, for me anyway. I've been able to manage going through a day full of busy away-from-home activities (even during cruise ship excursions!) by using the oil every hour or so if need be. That being said, whatever is going on these past few weeks I must say that the oil has not been as effective as during most of the past 4 years. Can't wait to see what the ENT comes up with when I go back on Monday. I have a hunch that I might be heading in the direction of another CAT scan, etc.
