Drank my first Red Bull yesterday, too!! Drank it before riding from the house to meet the club. From that first sip I experienced the carbonated PixieStix flavor mentioned in the other Red Bull thread. I didn't experience wings, but I do suspect that it had a lot to do with me being able to do 50 miles at an avg. of 17.3 mph, despite waking with a wicked sore throat and lungs that felt half full of fluid.
I had barely slept, due to my throat being swollen and sore all night, or at least until 3:30 AM, when it dawned on me to take some Vitamin I for the pain, inflammation and swelling. Then my son had growing pains and was crying, yet wouldn't take the Tylenol that would make the pains go away. Then my alarm went off at 6:45. And I hadn't done this distance in three weeks, and have barely been riding at all. Point being, I was not in top-notch condition for the ride. Yet I pulled it off, didn't get dropped, and maintained what for me is a pretty brisk pace!
Red Bull gets the fixedgeargirl seal of approval !!!!
