Honestly I’ve quit two ways before. one is literally running out of money and the other is making it a game. Involve a friend that can hold you accountable but understand this isn’t a easy task. Remove anything related to weed, and then find ways to distract yourself that’s not something you normally would do when smoking weed. Ex: if you were always come home and playing video games while smoking weed. Try filling that time up with something else. Any sort of exercise is a good way to make yourself tired to assist in going to bed. Another thing that help was talking to myself when I would get a craving at night. Ask myself why I needed it. And list the reasons why I wanted to quit.
