Alcohol addiction is a bitch, but nicotine is easy. I can recommend Alan Carr. Not to follow the programm religiously, but the general idea of it was very helpful to me. You just need to find your internal motivation, convince yourself that you need to stop. Whatever reason works for you. Maybe it’s your health, your kids, the money or just because it’s not cool anymore. For me it was the money, but money wasn’t actually a problem. However, it did work to convince myself that I needed to stop. Haven’t smoked in 4 years and it still brightens my day every day.
