Andrew:
Thought I'd share one thought with you.
I'm in the middle of my count now.
What I'm finding difficult to remember is:
I dare not focus on what I'm NOT doing, or NOT supposed to be doing.
When I think of NOT doing P** or m** or whatever, that takes over my entire brain and I can think of nothing else.
Instead, I'm having to think of things to REPLACE that empty space in my head.
What I want to DO, to THINK, to ACT.
I'm hoping that the new thinking will take away any CPU time inside my brain for anything else.
Or, you could try it the other way around: Tell yourself "I will not think about elephants for 90 days."
Good odds you'd be spending all day pushing elephant thoughts out of your head. And probably not very well, either.
Anyhow, that's one man's view from 45 days. Your mileage may vary.
