"Sins"?

[Angrboda]

When I was quitting smoking, I wore a rubber band on my wrist, and every time I'd think about smoking, I'd snap the rubber band and it would interrupt the thought. There's also cognitive behavioral therapy (some of which is self-help, like the book "Feeling Good" by Dr. David Burns). You might also immerse yourself in atheist culture (perhaps by reading Christopher Hitchens' "God is not great" - it's a good read).

Don't know what kind of help you need, but as said earlier, time is a good healer.
