the chronic lack of sleep

well it is the witching hour once again and i am bleary eyed and bushy tailed, when i should be happily sawing some termite ridden logs.  i wonder if insomnia has fueled any top selling writers....or is recharging at night essential for the creative outlet experience...cant seem to pinpoint the cause for this several month long bout with insomnia....partly physical and mostly emotional, i suspect...stress has many guises and can manifest itself at any time.....it is hard to imagine that i used to sleep so well and soundly, that, many years ago, i slept through a fire in an apt building i lived in.......
