Fin,I doubt that there is a real way out of this place, once hooked one tends to remain hooked although some do seem to manage to withdraw for a short while and maybe even post less frequently. You are in a trap and there is no way out!
I even tried meeting Morticia and Micca at Llanstock last weekend (not to mention LTS and many others) and even that was not enough to scare me off ;-)
