After a few hours of lurking on my occasional sites, I came across 5 Hour Energy's web site. They are giving away free samples of their strong tasting energy drink in hopes that you will buy more. So take advantage of this offer and send a free sample to all of your friend's houses!
The link is below will take you to the form you have to fill out to receive the offer. Remember to only drink a few of these a day. One of them is equal to 2 cups of coffee!
