Once you've quit, the next step is to stay off. The first three months or so after quitting are the hardest time. Most people who return to smoking do so then. During those first three months, they've broken the physical addiction but not yet shaken their psychological dependence on cigarettes.
It often takes just one cigarette to put you back on the smoking treadmill. Have some ideas up your sleeve to fight temptation. For example, plan to take a bath, chew sugarless gum, sip some water, find something to do with your hands, or step outside for some fresh air when the urge to smoke hits you.
If you know you are going to be around smokers, be prepared. Practice an answer for when you're offered a cigarette. Seek out nonsmokers in the group. Don't apologize for not smoking.
If you do smoke a cigarette, then you need to renew your decision to quit. Focus on learning from your slip, not on berating yourself for it. Figure out why you slipped up and how you might avoid doing so again.
Once your body's metabolism returns to normal, you may put on a little weight. The average is about 7 pounds. If you are worried about gaining weight, talk to your dietitian about changing your meal and exercise plans.
You also need to stay in touch with your health care provider after you quit. Your diabetes control will probably improve. If so, your health care provider may want to change your insulin dose or diabetes pill schedule. Similarly, if you are being treated for high blood pressure or high cholesterol levels, your condition may improve so much that your health care provider may want to change your treatment.
Remember, quitting smoking is probably the most important thing you can do for your health and for those around you.
