i thought wrong

so i thought that since i had successfully flown to australia, surviving a 21 hour flight, that i would be able to fly to england without falling victim to jetlag. certainly, in comparison, flying to england is nothing. forget that the other times i've flown to england i've had jetlag. oh no, why should that be taken into account. i made it two days functioning normally, and now it is 3 am and i am wide awake. i have written several postcards, finished an entire book, and checked my email. is it because i didn't drink this evening? does drunkenness cure jetlag? maybe. studies so far are inconclusive. woe is me.
