Tank question

[Noone]

As far as nitrogen goes should I get a second tank just in case? Also how much room do I leave for the bag around my neck? I've read it can't be too tight. Thanks again all

There is lots of videos on line how to make an exit bag and how to use a tank - the pressure gauges you need, the flow etc. The Peaceful Pill eHandbook should help further with instructions. A second tank is not nessisary. The Tank was my second option (first being N). But I am unable to obtain it due to the fact that I don't have a car and have a payee.
