When you start freaking out take a moment to INHALE really deep just like you do when you are taking that first drag in the morning. Then do it a few more times. It really helps with the stress you are feeling. (I realized that was the only time I really did any deep breathing!) Remind yourself that you won't die, even if it feels like you will. And think in threes: first three days are the worst, then much better. Three weeks and you quit obsessing; three monthes and you will be enjoying that tank - and wondering why you ever smoked in the first place!
