Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Omfg I once took a hit of CO2 as I thought my CO2 capsules were my N2O capsules.
Fuckin' 'orrible
Laughing gas is sweet and soft, taking a hit of CO2 is like choking on cactuses.
I had exposure to tear gas in the army and while it was a milder version (simulating mild-moderate exposure), I definitely preferred it to CO2.
