Program arm	Example text message
Pre-quit	When and why do you smoke? Start a smoking diary. Keep track of when you smoke, what you're doing (the activity), how you feel, and your craving (from 1-3).
Quit day	Withdrawal symptoms are unique to everyone. Frustration, impatience, and depression are common but usually only last a week or two.
Early quit	Treat every day like your quit day. Pretend as though it is the first day without cigarettes and be ready for temptation.
Late quit	Call your “special supporter” and make plans for your 2-week anniversary—it's just 3 days away!
Relapse	Becoming a non-smoker is like learning to ride a bike—it's hard at first and then you learn how to do it—and enjoy the ride!
Encouragement	Whatever you decide about smoking, believe in yourself. You CAN quit smoking if you put your mind to it and have a plan for success.
