it's hard, most will always struggle with it, I quit a few times and this most recent stint is almost 2 years. I have the odd one when I wanna kill something and it helps, then I dont touch them again for months or years. most people can't have 1 and walk away. I don't recommend trying. keep yourself busy, and avoid your triggers. most common are getting into the car, eating, and coffee. you can't avoid 2 of them but if you keep yourself busy with other things it'll help. chew gum, munch on candies or mints while you drive instead. it was mentioned earlier you have to want to quit.
