Thank you MesaMan, fripfrop, Bryn, dwtbd, tursipos999 and MythOfSisphus, for all your great advice and information.
It's also reassuring to read that others have succeeded by applying AVRT. I must admit to harbouring fears that it wasn't effective, then you all arrive with an input, evidencing admirable successes!
I've tried an alternative, worked the steps, to no avail. I like the concept that I have the power, particularly having recently researched the current research on neurological/chemical/physiological basis of alcohol addiction; the application of AVRT makes sense to me.
I just need to summon the courage to build up my psyche towards making a Big Plan, as I know if I fail, the Beast will shred me psychologically and proceed to use a new failure as a further tool, to ensure I continue drinking.
