Study Buddies?

A test is coming up.  Scratch that, three tests are coming up.  All on the same day.  You feel like you have no time to prepare.  Every moment you try to study, you end up passing out no matter where you are - desk, couch, floor, library...  What do you do?
For a lot of college students that answer would be artificial energy.  Whether it be coffee, redbull, 5 hour energy, or drugs, students are leaning on these stimulants more and more.  I'm included in this too!  I can't get through a long night of studying without my starbucks double shot espresso or a redbull...or maybe both.  These energy supplements cannot be good for our bodies no matter what they say.  Commercials for 5 hour energy try to make their product sound healthy.  Taken from 5hourenergy.com, their shot has "zero sugar, zero herbal stimulants, only 4 calories, and B-vitamins and amino acids."  But then, if you read the fine print, and you really have to look for it, they say to "limit caffeine products to avoid nervousness, sleeplessness and occasional rapid heartbeat."  Rapid heartbeat?  That sounds awfully dangerous.  And I don't need to mention the danger of taking drugs.  Although many students use adderall - the "study drug" - there can be many side effects.  Adderall is a powerful stimulant and has a risk of sudden death, stroke, and heart attack.  Is cramming for a test really this important.  Why not just take the good ol' natural way and try to keep a healthy diet, exercise, and (try to) get enough sleep.  Don't ruin your body over studying.
