For symptoms:

Mom made me a shot of whiskey, honey and lemon juice as a child. (We did not drink in my household. Ever.) Works a charm.

My wife makes me hover over a steaming bowl of salt water, towel over head. Does seem to work well. Can’t hurt to expand your lungs with the hear and get some salt air in there, right? A trip to the beach, especially in the water, cures a great many ills.

The cure:

What breaks my fever is curling up in bed under a ton of blankets and knocking myself out. When I get to dreaming heavily I’ll wake up soaked in sweat. Not mildly moist, I mean to say soaking wet, really gross, have to get up and towel off. That’s how I know I’m on the other side and getting better.
