how not to fall asleep while mugging

HEY KIDS. due to the overwhelming response to HOW TO SURVIVE A BROKEN FINGER, I now bring you the thrilling sequel on how to survive something else, something a hundred times more painful. I bring you

HOW NOT TO FALL ASLEEP WHILE MUGGING

MUSIC
By music I mean of the heavy metal variety. You don't want to be listening to smooth jazz and hope not to fall asleep. What you need is a nonstop auditory assault of bone crunching drums and distorted riffage. Whether you can concentrate is another matter altogether, but that's not really the point of this guide.

EXERCISE
Drop 20 whenever you feel the Zs coming. But effects are very temporary. The moment your heart rate goes back to normal so does your tendency to fall asleep

CAFFEINE
A very popular option is caffeine. But caffeine they say impairs hippocampus-centred learning and long-term memory loss and I'm pretty sure it even causes cancer, though research hasn't been done on that as yet (it's only a matter of time) so a good alternative would be Berocca, which is sort of like a vitamin-based Red Bull. The only problem is it makes your pee a rather disturbing shade of yellow. (due to body excreting excess vitamins)

LOCATION
Don't even think about mugging in your room. Too many distractions. Here's what you do: get a seven-foot tall ladder and sit on top. (courtesy: Wai Yee) If you nod off, you fall off. If that doesn't work, try the window ledge - that'd definitely make you appreciate the gravity of the situation.

MASOCHISM
The moment you feel yourself drifting away, punch/pinch/slap/lynch yourself. If inflicting bodily harm to yourself is against your religion, employ a suitably sadistic friend.

AND IF ALL ELSE FAILS..
..give in.

..or get a good night's rest. But if you were already doing that then you wouldn't need this guide anyways would you?
