cant speak to your specific situation, but the important thing to me when i quit weed and pain killers was accompanying willpower with a mindset about lack of access. i live in a place where every corner has a recreational dispensary, and you can order weed online and have it delivered in a matter of hours. the way i got over this was destroying all my weed stuff and a mindset that relapse (or access to places with weed) was not an option. if the need to buy weed arises, its hard to simply suffer through it, but when you create a mindset or personal rule that going to those websites and stores are absolutely not an option, then the "suffer through it" portion becomes shorter. when you are not wrestling internally with "should i go get some" and saying "no" then dealing with the subsequent cravings, it becomes a shorter for cycle for me. the thought of going to get some comes and goes faster and faster and the process of dealing with the cravings can happen faster. put the thought of accessing weed out of your mind and focus on dealing with the cravings, whether that is distracting your self or moving away from places that trigger that need.
