The first time I was badly narced, I didn't have any idea that was what was wrong with me. I was doing a dive on a local site that I knew pretty well, but we were going deeper than I had gone before. I was with two other divers who I didn't know well, but trusted. Visibility was very poor. I got confused about where we were going, and felt anxious about everything looking the same around me (which it does, in transit, in that site). We got to the destination (a log pile) and I became completely convinced that I was about to begin an uncontrolled ascent, so I dumped all the gas from my wing and my suit, and went kersplat! into the silt.
The second time was at similar depth in the same site, where I became convinced that my regulator was malfunctioning and not delivering air as it ought. That time, I knew what the problem was, so I told myself just to keep calmly breathing and I would be fine. The little voice in the back of my head was hard to silence.
Nowadays, it appears that my narcosis symptom is pretty much a low-level, floating anxiety or feeling of discomfort. Again, I never realize it's narcosis until I get to the surface and think about the dive in retrospect. I have also been completely comfortable and simply made really stupid errors, usually of omission.
