Pricing jetlag into the fee

1am in Ortigas City, the affluent precinct of Manila where I've been staying since I arrived in the Philippines exactly 72 hours ago.  I'm wide awake and out of Stilnox (aka Ambien).  I've only eaten lightly, used the hotel gym and self-medicating with red wine will only make the waking hours harder.  I'm 50% through the project.  Tomorrow I fly to Seoul to repeat what I've just delivered only this time via a (client-sourced) interpreter who claims, but only when chased, that she still hasn't received my slide presentation.  Interpreters are often hard to deal with and this augers poorly for the rest of the week.

I tell myself to suck it up.  Self-employment means that in the end every problem belongs only to you.  The only sane response is to price interpreter angst and the inevitability of jetlag into the fee.
