Hi Nich, good to hear this is working out for you. I'm always interested in how long periods of abstinence works with starting on TSM. In theory it should work just fine and it seems that it is for you. I'm curious about a couple of things, one is what kind of drinker were you? Daily? Binge? 20 drinks a day or only 5? and also I'm curious what was going on through your mind that made you want to drink again after 6 years. Or perhaps it was always on your mind?
In Eskapa's book he compares AA to the prison treatment method. If you are an alcoholic and you break the law, say kill someone in a DUI accident, and then get shipped off to prison for 5, 10 15 or however many years you still remain an addicted alcoholic. You simply flip the switch and stop drinking but leave the brain in the same alcoholic state from the very first day in prison ready to be switched on again. That's exactly what AA does, it simply cuts off your drinking and tries to force abstinence. TSM actually causes a physical, biological, chemical and as such psychological process in the brain that literally rewires it, as you saw in the movie. Read the book too it's got some great incite into how this process works.
I can only speak for myself when I say it works 100%. I still drink and my levels go up and down on occasions but I have not once hidden drinks, had severe cravings, withdrawal and in fact can honestly say I've only been sort of drunk a little bit once in the approximately 20 months I've been doing it. That's compared to being pass-out, black out drunk about 350 nights per year.
It's so incredibly wonderful to have a glass of wine with the family on Christmas eve and not have to supplement that with 8 shots of vodka, several pounded glasses of downed wine, and probably a few beers too

I mean seriously even after all this time I have to pinch myself just to know that it's real.
It's not too good to be true. It just is true.
Good luck!
