I'm with the 'finally just left' comment.
Either just stop cold turkey with the meetings or go down to every other Sunday only for a couple of months or something like that.
It seems you have set the stage to just quit. Good for you!!! How much hassle you get will probably depend on the dilligence of the elders (ie. they may look u up at CO visits when they have to give a publisher report) and how many in the congregation will miss you (how much you were liked). Otherwise you are home free ... get busy living your life ... there is so much you can do with your new found freedom. The mental freedom may take a little longer to actually get but why not go ahead and enjoy your physical freedom.
