You have been huffing too-much bear spray, knock it off! :biglaugh:
I never drink more than 1/2 bottle per hour, or my vision goes black and white. Then things get weird. Bike seems run like a scalded cat after 2-3 bottles though.
I would suggest starting this only if you have Friday off, and can use the weekend to recooperate. I feel clean as a whistle come Monday morning.
