It takes a while for blood pressure to get up in the morning (allegedly slower in blokes). On livaboards I find a walk around the deck a couple times before breakfast can make a big difference.
I don't rush any descents these days. A brief stop at 3m to get my crap together and relax, a gentle fin down and a pause on the shot whenever I feel I am working too hard.
Yep, done the tunnel vision thing. It is not so bad, I just stop, breathe and hang on tight until it subsides. The total blackout is what scared the crap out of me. There is 2 minutes, a 10m descent (from 30m ish) and a 20m ascent, completely missing from my life. My computer assures me I was there. I was not very experienced in those days - not enough to know when to stop following a buddy. |
Thanks for that - some practical advice.
I first realised I was getting narked in the pit at Stoney - I suspect it was a CO2 reading other replies as it was a definate bum clencher! Itcleared mostly as I went up but I was a lot more settled when I got to do my stop at 6m. I hadn't noticed being narked before - but looking back I was a little on the UC70 last year - I didn't feel fully in control at the bottom but again got better as I went up - that was probably a nitrogen hit I guess.
