I love this stuff. I drink it all the time and it really does help me boost my stamina at work. If I didn't get much sleep the night before, I down one and within 45 min or so, I feel refreshed. The taste took some getting used to though, but once I did I came to enjoy the taste quite a bit. Does anyone else here drink this stuff? I also wonder if it's effects on me are merely a form of mental suggestion or if it really contains something that gives me more energy.
