First, a hello to everyone, I think this is actually my first post.

Anyway, my daughter and I are relatively new divers, we always dive in Coz together, neither of us has ever been narc'd, but on our last trip one of our group got narc'd and it scared the crap out of both of us. We were doing Palancar Bricks if I remember correctly, down around 100' or so, I'm tail end Charlie in a group of 6 divers, my daughter is right in front of me. In front of her was a sub-group of 3 women.

We come to the edge of a wall, all of a sudden one of the women goes over the edge and starts kicking straight down. I'm looking at her, thinking "*** is this woman doing??" The divemaster sees her and starts banging the crap out of his tank. No response. He goes after her, probably caught her about 140' or so. Pulls her back up to our depth, and he's giving her all the signals - "Are you OK?" She's nodding, giving the signs, all looks good. Until he lets go of her, at which point she reaches down and pickles both of her weight bags and starts shooting to the TOP like a cork now. The divemaster is right behind her the whole way, fighting to slow her down while the rest can do nothing but watch and wonder what the HELL is going on. All the way to the surface they go, we can barely see them.

So the rest of us kind of circle the wagons, thumbs up, let's go up, but SLOW. I fully expected to be boatless when we got there, I figured sure as heck the lady was bent over sick and they'd be flying to shore and we'd have to swim in or flag down the nearest boat. So we get up to about maybe 30', took our sweet time getting there, all of a sudden HERE COMES OUR DIVEMASTER BACK DOWN!!!!!??????? And he's motioning us to follow him, we're going to finish the dive??? Sure enough, that's exactly what we did. Maybe 20 mins later now we come up for good, here's the narc'd lady in the boat, and she's laying in the sun like nothing happened. Besides the fact, of course, that she said she had absolutely no memory of any of it.

So that was our first, and hopefully last experience with narcosis. What still boggles my mind is that the lady appeared to have absolutely no ill effects (besides the memory fuzz-out) despite what appeared to be a completely WRONG ascent. Lesson learned for both my daughter and myself, without question. We started paying a LOT closer attention to each other for the rest of that week.
 
it would be nice if there was some quick fairly accurate test that you could do during a dive if you think you may getting disfunctional. Simple math or reciting a limrick or?

Simple, swim a straight line, tilt your head back and touch the tip of your second stage with each index finger, and have your buddy shine his backup light in your eyes, moving it back and forth while you follow. ;)
 
Yes, Sue, you are buddy diving. Next time tell your buddy I said Hi!

Sure will :).... , but hopefully I won't have a next time and that buddy doesn't show up. It surely was bazaar.

And an instantaneous cure for narcosis in your buddy might be flashing red and blue strobe lights at him from behind...:D

Sometimes I get so narc'd that I think that my LDS has become a bazaar! Truly bizarre!

take a padlock down with you....... my daughter did this on her AOW class deep dive. It was funny because she forgot that you have to spin the dial around 3 times for first number, 2 times for second.... she remembered the numbers, just not the sequence. :doh2:

another good one is a math problem written out on a slate. Those are the most common "tests" I have seen done. It is good to have a second diver along who times you. There are also some puzzles that you can put together, but most people don't want to take those on vacation with them!!!

One BIG thing about narcosis = sometimes you get it at a certain depth, another day you may not. It has alot to do with hydration, how rested you are, how many dives you have done deep dives in the previous week (some people believe you can build up a resistence to it by doing successively deeper dives each day over a week), also how much alcohol you have consumed recently, how recently you have eaten, and your general health. I have a friend who is diabetic who gets narced below 30'. She just can't function in the water anymore so no one will dive with her because she is unsafe.

:D
 
I wonder if there's any coralation between how well one handles alcohol and how well they handle narcosis? I have a really high tolerance to booze, as my usual drink at the bar is 151 and diet coke. I know I'm under the influence after a couple, but I don't really feel it. Maybe it's the same for me with narcosis? I've been diving since 1988 and have done a whole lot of dives way deeper than 100 feet and have yet to notice anything?

some say yes..... personally, I just think you are someone who doesn't think they are impared with either. Everyone gets narced below 80-100', but to different degrees. Some people get hit in the head with a hammer, others it is very gradual and they don't notice the effects until much deeper.

I never said I don't think I'm under the influence, in either case, and it's not some macho statement either. I just don't notice it with narcosis, and it takes quite a few before I notice the affects of alcohol as well....

I'm one of those dive buddies that spend half my dive keeping an eye on the lesser experienced members of my group, and so far I haven't forgotten to keep an eye on their air consumption and even alert them when they're getting low if they didn't notice, and that's at all depths. I keep wondering where the edge of that envelope is where I actually notice narcosis, but I'm not about to push it to find out......
 
I remember my first narc. Me too, was about 100 ft and went to being fine to "Here Fishy,Fishy, Fishy, and seeing 4 pairs of flippers in front of me and wheeeeeeee. I just happened to look up toward dive master and he saw what was going on I guess and signaled me up a little, and 10 ft up I was fine again. Haven't narc again and that was about 140 dives ago. I've done 129 ft in Cozumel and no problems with narc. I agree it just depends on all situations.
