Fast acting caffeine, but not TOO fast =)
Actually, I expected it to make me cough, but it mostly didn't. The taste is nice, it's not too spicy, and seems to work (though it does not hit me like a truck or a &#34;rush&#34; as i feared. This is a good thing, haha)<br /><br />Bonus: Made all my friends roll their eyes SO HARD they almost fell out.  This is a feature.
