About the only thing currently capable of keeping my right sinus from itching - and I'm talking about give-me-razor-blades-on-a-stick-to-scratch-with itching - is regular overdoses of vicks inhaler. As in, stick the thing in my right nostril for a half a minute or so. preferably with the left side blocked. It works for half an hour or so. Good thing I don't get addicted to this shit.
I suspect I'm just about past the stage where I'm meaningfully infectious. I think most of that was yesterday. Today is mainly misery. Tomorrow will be - I hope - less misery, and more house cleaning. I should be fine - or sufficiently close to it - sunday.
