What I invariably say right before my second to last cigarette of the evening...

...And what I thought just thirty seconds ago.

It's an excuse to stretch my waking hours just a little bit further - because I enjoy the feeling of being tired far more than I enjoy settling down and tucking in for the night. And that last (or second to last) cigarette seems to always brings me back up to the point where I'm physically weary enough to feel everything drag, but not weary enough to give up on it all and give in to sleep.
