If explorers had shrooms, weed and some way to play music, I think they'd be good.
Unfortunately there is still a "no fun" camp at the head of decision making.
…though I think your point is, that while you're stuck in ice with no way out, all the mental stability structures you build to connect yourself to reality are bad and harmful. And being on drugs and disrupting your reality, breaking down your preconceptions etc. would be more along the lines of continually breaking down the BAD mental structures you're inevitably building, due to correct appraisal of your situation.
Still doesn't sound awesome though :)
