George, Two weeks ago I showed myself, first hand, just how insidious narcosis can be. We were diving an area of a flooded mine at 36m (118ft). I had arrived late and wasn't able to arrange the mix I have used in the past (28/10) and, stupidly, decided to dive Nitrox 28. As I hit the 36m level, I could feel a slight narcosis buzz. About halfway through the dive, we were exploring a side tunnel that had an alcove in it with a 45-degree shaft in the floor joining it to the level below. I went in to the alcove, looked down the incline shaft and then began to slowly turn around in the tight space. While I was turning, I stirred up a little silt and simultaneously sank a few meters into the shaft. To say the least, it was a big surprise not to see my buddies or the line (only empty passage in the level below) I was now at 39m (128ft). It felt like I long while before I realised what had happened and re-traced my steps- to find my buddy waiting. The whole incident took, perhaps, 30 seconds, but I am quite sure it would not have happened if I had been diving the correct mix.
