Hey MB8.
The future is not written, my friend.
Just because you drank at the 6 month stage before does not mean you have to this time.
Part of you wants to "fail" as you put it, of course.
That's why you say "every time I get to six months I fail".
Try saying "in the past I've failed to get by the six month mark".
But you have a great advantage this time- you realise you're making excuses to drink.
It's only that addictive voice.
It doesn't want anything good for you.
Resist it.
I wish you well, amigo.
