Athletes who have taken Vyvanse (or other stimulants)?

Hey there,

I started taking Vyvanse about a week and a half ago, and for whatever reason I stopped my cardio then as well. Tonight I was trying to play hockey and within about 2 minutes of play my heart rate was through the roof, to the point where I pulled myself out of the game.

Now, I've fractured my arm before and kept playing until my line changed. So I don't quit easily. But my heart was going faster than it ever has tonight. I fully intend to talk to my doctor about it later this week, but has anyone else had something similar happen? If so, what we're the results?
