I agree that narcosis is not something you want to fool with, taking your regulator out of your mouth and swimming off is not unheard of. I would place intentional narcosis diving in the same domain as diving while seriously drunk in terms of your likelyhood to screw up and drown or bolt for the surface.
BTW, seeing as you live in St. Croix, have you dived on "the wall?" I did that one around 94-95, spectacular!

Grant, I dive on "The Wall" on average about once a week. I never get tired of that dive. It's exactly 150 kicks with each fin to get out to the bouys.
We saw a manta ray there last week that had to be 8 feet tip-to-tip. There are almost always turtles, sometimes eels, plenty of exotic tropicals, warm water, great visibility and air fills are $3 at the Cane Bay dive shop. There's also a nice place to eat overlooking the beach.
All of the good scenery is at <75 feet. The Wall drops off into infinity, so the tempation is to test yourself. But all the good sites disappear quickly, so there is no real incentive to go below about 100 feet.
