i nailed a ripper back in 99. when i tell the story, my pulse still quickens and i start talking really fast. i can still tap that rush after 6 years. it is a great feeling.
i was "high" after the kill for a solid week before i started to calm down. i would wake up in the middle of the night giggling.
enjoy yourself. it may not happen for a while; then again, it could happen again really fast.
