I’ve noticed that if I say “I won’t do this anymore at all”, it doesn’t work. But if I say “I’ll only spend this much this month on sex workers, gambling, etc.” I’m able to mellow down. I’ve also noticed some people suggest that moderation doesn’t work and you should try to be as cold turkey as possible.
This person weaned off instead of cold turkey for the same outcome: cessation.
Moderation would be if they still smoked 2 cigarettes a day or a couple times a week instead of 2 packs every day.
