Nothing I've tried works better on a purely physical level, and in clinical trials, nicotine replacement therapy was shown to double your chances of successfully quitting versus cold turkey. The patch functions by transdermally feeding the body nicotine at a continuous and regulated pace over a 24-hour period, controlling the body's physical addiction which allows you to sever your mental reliance on cigarettes without killing someone. You still have habitual cravings, but they're relatively tolerable. Since poverty was one of the reasons I quit smoking, I opted for one week of 14 mg patches. I had no adverse reactions, save for very minor and transient skin irritation, although side effects can include irregular heartbeat or palpitations, rashes, nausea, vomiting, dizziness and weakness.
Most people resort to food, although smokers only gain about five pounds on average when they quit.
Whenever you have a craving, you put 20 drops under your tongue and hold it there until it's absorbed. My colleague Terri, who also quit recently, liked the tincture as well. It tastes horrible and burns like crazy. It also makes you slightly queasy, which checks both food and tobacco cravings. It's distracting and viscerally intense like a cigarette, and it offers a similar calming and focusing effect.
