Yeah, we used to have a connect for Nos when I was a kid, we'd get 15, 20, 30lb tanks of it and just hang around with big punch balloons for hours. When you're done, chase a Five Hour Energy with some Gatorade and you're good to go. Five Hour Energy has 20,000%DV of B12. It was crazy how rapidly you went from feeling dopey and tired to good to go. I would go play hockey games an hour after sitting on nitrous for two or three.

All that being said, that's the inherent danger in nitrous, it is way too easy to do. Hangovers are nature's way of telling you not to fuck with shit too much. You can all but eliminate that from nitrous, and that's no bueno.
