Insomnia

I'm 3 hours into a 4 hour layover in Seattle and I'm trying to weigh out whether I want to get a drink or not.  If I get it, my thirst will be quenched, but then I might have to go to the bathroom on the plane as soon as we take off.  If I don't, I could wait for free drinks on the plane, but I have to wait... Decisions decisions...
