| Every single dive below 20m - the first thing to go is your judgement so it's incredibly easy to believe you aren't affected.
If you don't believe you're narked at 20m, get your buddy to prepare a few simple maths questions on a slate and then time yourself to answer them. Then have a barrel of laughs when you check the answers...
Cheers, Chris
