The 5 Hour Energy Shot does everything it advertises. I have used it many times, mostly for roadtrips. You really don't feel energized as much as you do alert and free from any signs of drowsiness. I don't believe that the product has any uncomfortable side effects, but I do believe that taking this shot when you are truly exhausted leads to an unpleasant experience. After a night a drinking, a day of snowboarding, and a long drive back from the mountains, I took my second 5 Hour Energy Shot of the day so that I could continue my boisterous birthday celebration. I was so physically drained that I could have slept through just about anything, but not a 5 Hour Energy Shot. Fifteen minutes after taking the shot, my incessant yawning stopped and my drooping eyelids lost their weight. However, my body entered into a battle with itself and my mind, unable to decide whether I was depleted or rejuvenated. It is a surreal feeling to be so utterly tired and yet so alert; I did not find it overly enjoyable.
I recommend the 5 Hour Energy Shot as boost for some extra productivity or as a safety precaution when driving long or strenuous roads; it is excellent for immediate and long lasting attentiveness. I advise against using the 5 Hour Energy Shot for extended stretches of debauchery or re-animation.
