Nerves

20 hours to my thesis defence. [edit>> thesis defence time: 9 March 2010, 10.30am]

but i'm already experiencing all the physiological effects of anxiousness...
butterflies in my stomach.
tense muscles.
reduced appetite.
loud heartbeats.
blank mind.

and as always...i feel, on and off, the urgent instinct to flee but immediately pushed down by the will to act, to fight.
the fight or flight response...gawd!

i need to practice my presentation.
i need to read all the journals again.
i need to refine my slides.

i need to calm down.
