Lots of swearing, emotional buzz probably just adrenalin, then a period of near obsession with it. Feelings can swing to anger and back to happyness several times before settling down. I remember the good feeling that came with the sheer mental freedom to actually question everything in my own mind and allowing myself to say out loud to myself thoughts and words forbidden by the cult. Simply vocalising the phrase "it's a f@cking cult" for the 1st time was cathartic.
607 was the killer blow for me, I'd seen plenty of fluff (from my viewpoint at that time) as to what was wrong with the WTBTS etc and nothing really clicked until I got down to solid proof that a foundational doctrine was utter bollocks.
