It’s difficult to switch straight from a normal sun-driven schedule to one in which you’re sleeping while the rest of the world is awake. Doing this will likely just leave you completely sleep deprived, since you’ll force yourself to stay up all night and you won’t be able to sleep well during the day.

If you don’t want to go outside, do sets of crunches, situps or pullups in your house to keep yourself awake.  Taking a shower after you work out, preferably a cool one, will also help keep you from falling asleep. If you don’t like to exercise, just stick your head outside and take...
