I agree with Harlem and WhenWillI.
Because control begins with taking it.
And no one I know would be offended at an AA meeting if you went in and said, 'It's simple, just stop drinking,' because well, that's why we're there and that's what we're doing!
And yes, it really is like that: every day, you say, 'I will not drink. Only for today. Tomorrow is tomorrow but today I won't drink.'
It can be applied to a lot of things in life: Today I will take some responsibility for my life. Today I will not lie.
But as someone who struggles with depression, I, too, am offending by comparisons of having an affair to substance abuse or mental illness.
If you don't take responsiblity for what you do, none of this 'swept off my feet' bullshit, then you can expect it to all end in tears - mostly your children's.
