Use the correct nicotine-replacement dose
Chewing gum, patches, lozenges, sprays and inhalers containing nicotine can all be helpful. They all release nicotine very slowly into the bloodstream, easing symptoms of withdrawal without all the other toxins in cigarette smoke.
Studies find that the patch increases quit rates by about 7 percent compared to a placebo, the gum and inhaler by about 8 percent, and the nasal spray by 12 to 16 percent. But make sure you’re getting enough. If you smoke more than 10 cigarettes a day, for example, choose a higher-dose (usually 21-mg) patch. And if you have your first cigarette within half an hour of waking up in the morning, start the day with a 4-mg lozenge rather than a 2-mg dose.
If you still have cravings, using a patch plus a faster-acting product such as gum, lozenges or a spray or inhaler can further boost your chances of succeeding, according to experts.
