Make changes in your routine that are reminders.
Don't smoke in your "regular" place would be
an eXcellent start.
If you normally smoke in the patio, go smoke in the yard.
If you sit in a particular chair, go smoke in another chair.
Do you see how this would work?
It breaks the "normal" pattern.
It reminds you.
It gets you off autopilot.
It shows you you can change.
It prepares you to quit.
Once you get going you'll realize,
YOU HAVE THE POWER!
