Oh, ok...it's simple really. Drink a whole family sized bottle of Nyquil, Robitussin, whatever then crank the heat and get under a bunch of thick blankets. You'll likely hallucinate before you pass out, sleep extremely deeply, and sweat nearly any sickness out. You'll wake up feeling 90% normal...if a little hungover too. It probably isn't something a doctor would recommend (neither do I for that matter really), but for me it works almost every time.
Edit: If you're stupid enough to follow my lead on this one you wanna' be sure you don't have ANY thing you have to do in the near future. You may end up sleeping as long as a day or two. Oh, and this probably isn't entirely safe.
