Take a cold shower, remain naked with air con and fan at full
blast. If it still doesn't work, spend the next 5 hours
chain-smoking approx 2 packs of cigarettes or even more if you can
afford.
If all else fails, visit a mortuary - get a corpse, stab it
multiple times... Drink the discharge - you're bound to get a high
fever if not hamtam by the hospital staff and later on jailed for a
long long time
