I overpressure myself, as if I was constipated, each time I get cravings. I basically make my body as uncomfortable as I can so it learns that cravings=pain.
In the past, I’ve used hand rolled tobacco to ween myself off. It’s a lot harder to just grab a smoke when driving for instance. But cold turkey is best. I usually wait until I get sick before starting stopping since it tends to skip the nasty craving in the first few days. After a week or two, it gets much easier.
Remember, having a smoke every now and then will work until it doesn’t.
