Many who come here and disappear quickly obviously thought something magical was going to happen on quit day.
You have to stir up some differences for your brain to make changes that will work to remind you of your goal.
If you've decided to quit? Start smoking with your other hand until quit day.
Everytime you smoke you will remember you are going to quit and it isn't bad because you aren't missing out on anything. It will simply be a reminder.
Pretty simple huh? Try it, you'll see how IT WORKS!
