Head up, feet down - reduces narcosis.
Really? I've never heard that. Got any links I can peruse or is that just something you've noticed about yourself?

Head up, feet down - reduces narcosis.
Being drunk/stoned is typically less obvious sitting up than laying down. Ever got in bed and things start spinning?Really? I've never heard that. Got any links I can peruse or is that just something you've noticed about yourself?
I'd guess that it reduces the impact of vertigo and aids orientation - both factors that can be heavily exagerated by narcosis. The narcosis isn't actually reduced, but the recognisable and debilitating symptoms are.

Well, if you take the definition of nitrogen narcosis as "A stuporous condition variously characterized by disorientation, euphoria, and loss of judgment and skill..." then I would argue that is what is reduced
I think that narcosis is far more complex than that. The definition you quote is an 'ok' way to describe it to an open water student.... but (as you know) deep air diving brings about a greater understanding of how it influences you.
I did lots of deep air diving and thought I was fine, until a minor issue occured and made me realise just how much narcosis was effecting me on those dives. At no point did I feel disorientated, euphoric or lose skill. I did lose about 2/3rd of my IQ points though.
Here's a good thread that describes the less obvious onset of narcosis..

I don't disagree, but the distinction I was making was between the narcosis itself, and the cause of the narcosis ie gas under high partial pressures. There seem to be a lot of people who confuse them or think they are the same, hence you get people saying you can't 'manage' narcosis
