I just read "Shadow Divers" and they had a really good description of narcosis in there. I had never heard of the phenomenon they called "jungle drums" which is the sound of your pulse beating in your ears. I always attributed that to wearing a hood whenever it happened but it didn't happen all the time. I've been "badly" narced twice, the first time was in warm water as I was coming up from a 100 foot dive. I was at 80 feet and suddenly everything was hilarious, I couldn't wipe the stupid smile off of my face. I figured out what was going on and told my buddy we needed to ascend some more. The second time was last weekend in Lake Huron and it was ugly. We were on the Regina and my buddy and I had gone from the stern to the bow and we were heading back when I asked my buddy how much air he had. He said 1400psi and I had 1700psi, we were at the gash in the side of the wreck (at about 80 feet) and I knew we had plenty of air to make it to the anchor line and do our safety stops. I started to notice that my pulse was starting to pound in my ears and I tried adjusting my hood to make it quiet down but it wouldn't, no big deal. Suddenly I felt VERY anxious for no reason and I tried talking to myself to make the feeling go away but it just got worse. I started to hyperventilate and told myself that I couldn't do that, after about 15 seconds I managed to get my breathing under control and let my buddy know that things weren't quite right. I started having a strong urge to get to the surface, I just wanted to be out of the water. I told my buddy I wanted to go up a little and we ascended to about 70 feet. My buddy was checking on me regularly asking if I was ok and I kept giving him the "so-so" sign. Suddenly I had this violent urge to get out of the water. Part of me kept saying, "Screw the anchor line and safety stops, just go to the surface!" I told myself that wasn't an option, I was to stay down and proceed to the anchor line. The urge to panic and bolt for the surface kept getting stronger and stronger but I managed to hold my position and continue swimming for the anchor line at a relaxed pace. The next thing that happened scared the bejeebers out of me, I no longer wanted my regulator, I didn't want that thing anywhere near me. I knew I was getting air I just didn't want the thing in my mouth and at that moment I understood why some divers who panic and bolt spit their regulator out and won't take a regulator from anyone else. I told myself, "You are NOT going to blow and go from 70 feet, your instructor will kill you if she finds out you did something like that and she WILL find out!" I looked at my buddy and gave him the "up, up, up--level off" sign and we slowly ascended to about 50 feet and swam along the top (actually bottom, the Regina is upside down) of the wreck. We had only been there for about 10 seconds when all of those feelings went away. I finished the swim to the anchor line and we did a normal ascent with safety stops and exited. I can tell you one thing, I NEVER want to go through that again but I did learn a lot from the experience.
