- all you have to do is not smoke for about six days - afterwhich all the toxins are out of your body so you should not get physical cravings any longer. Only the mental cravings are there - they are harder to combat as that is what the 'habit' is. Best thing is to think positive, you are now a non smoker. Yes play with your fingers - or toes - get up and do something else, call a friend, do some exercise, do whatever for the mental image of a cigarette in your hand to subside.
