I would love it if camping, sleeping, meditation and the like added an effect
to 'show effects' for the time post-skill when one is unable to repeat the
skill in question. For sleeping and camping i suggest 'Refreshed', for
meditation 'at peace' or something. Or the effect could be just 'tired' to
indicate that you can sleep. This all leans on a couple of minutes worth of
thinking as I wrote, I'm sure someone can polish this into a gem.
Thank you.

Atleast you can write following stuff to your meditation command: use
meditation;grep 'You are not in tune with your inner forces yet.' help skill
meditation
Maybe that will do the trick...
