The idea of somehow trying to experience a "controlled" session of narcosis is something I have sympathy for. Myself I have decided that I will make every effort to do it in a chamber though, which means waiting until DAN starts doing deeper experiments (I live 20 miles from DAN) or finding another chamber that is willing to take people down. I've met a few divers who said that they've been to such chambers, that will take you down, but they lived elsewhere at the time. Of course some people just look at this idea and shake their heads. I simply think there are dives I want to do that are deeper than I've been, and so far I really don't feel like I have been narced. I might be willing to concede some physical reaction slowness, but on my deepest dives I have also felt very focused. Some people will say its just like having a few beers, that's fine but I don't feel like doing that kind of dive experience (having a few beers and diving shallow so I am narced). Moreso, I've heard (it could be false) that in a chamber (nice relatively safe environment) you can notice smaller, more subtle symptoms of narcosis since you don't have a dive plan competing for your attention. anyway, just some thoughts, Mike -- Mike Zimmerman < zimmmt@au*.al*.co* > Alcatel Network Sytems, Ral, NC *My opinions, not Alcatel's* [\] NC Diving: http://www.vnet.com/scuba/ A is A. Man who say it cannot be done should not interrupt man doing it.
