It happens to me every time i go on a crazy ride at the fair or carnival.
Heck. Yes.
LOL try waiting in line for Disneyland when I was little; I felt sick every time I was in line for a scary ride (Ie Haunted mansion, indiana jones). It still happens :) Like when I watched the Indiana Jones movie for the first time :)
Adrenalin usually drops your blood sugar, the rise may come later. That is how it works for me anyhow.
I never noticed it on rides, I will have to check next time.
But, I do notice it when I play hockey. After my game about 80% of the time my sugars are really high no matter what they are before my game. It doesn't happen when I exercise, so it must be adrenaline because of the game situation verses just working out.
I wonder if there had ever been a study on adrenaline and blood sugars?
Maybe you should spearhead one :)
