addendum.

One thing else to say regarding the whole giving up smoking thing. I have found that all my bad habits - smoking, drinking, throwing money at fruit machines, being a cynical bastard etc. - are all tangled up with each other, because of the way that certain behaviours reinforce each other. I go to the pub. I have a drink. I always smoke when I drink. I parch my thrat because of the smoke. I drink more. I smoke more. I get drunk....and so on, until I'm lying penniless in the gutter the next day, having caught some unspeakable disease and eaten a kebab from a converted ambulance along the way. Breaking the cycle is tricky, but once one bit has gone, other trends seem to follow.
