that's what (ahem) ratty said too 
i only lose all self-discipline in the face of coffee... i think
the last of the pills i was taking which caused the hunger got the
better of me.. was so hungry and the only thing within reach was
them choccies 
in other news, i think the abuse of caffeine is getting to me..
after 2 double expressos, i fell asleep in the bus, and then slept
relatively early last night..
