Stop in for a cup of coffee

I have too. First head cold in a couple years. If it turns into a sinus infection, off to the doc I go. Looks like It's heading that way.
You can try snorting a hypertonic warm water salt solution. Sometimes it knocks the bugs down well enough to let your body fight it off naturally.

You can also apply it by putting it in a teaspoon and snorting up each nostril while pinching the other one closed.
