Nope, no Wings

Yesterday as I grocery shopped, I was feeling a bit sluggish and thought about all the stuff I had to do yet in the day. I decided to try a sugar free Red Bull. First off, it has an awful taste to it, but I drank it anyway. Second, I didn't sprout any wings of any sort, nor did I get a burst of energy at any time. I did, however, get the shakes. I guess I wasted about $1.50....which I won't do again!
