Experts tell us that pulling "all nighters" rarely are effective in raising test grades. Newer research tells us that the best way to increase alertness is to drink a cup of coffee and then take a 15-20 minute nap. The nap clears the body of sleep inducing adenosine and gives just enough time for the caffeine to hit the blood stream.
