Passing out from aggressively blowing air into your sleeping pad is one way to fall asleep. A better way would be to try the Nemo Vortex Pump Sack. It takes no time at all to fill up and takes all the effort out of inflating your sleeping pad. It's also great because it eliminates moisture (your spit) from entering the pad, greatly increasing it's lifespan. Now you can fall asleep the natural way.
