i had a nasty iv cocaine/heroine habit, mostly cocaine.
the needle fixation involves a lot of ritual, the habitual habit personified. the only way i was able to get it out of my system the first time at 134lbs,, was lots of patience, 2 months in jail, 3.5 months inpatient, i lived with my NA sponsor for 7 months or so, then a half way house.
i would still fantasize and fixate.
find something to take this 'rituals place' like meditating before exorcising is great. or getting hyped to a song and then riding a bike hard, or running, lifting, yoga, palates, anything similar.
this would be to try and give you a physiological boost and one of self-pride, with some sort of order you take to prepare; which takes up more time and builds further structure.
discover new simple veggies and fruits/cultures.
this is a mental addiction, and it is very sneaky! because the peaks of wanting come and go with no warning.
i would avoid any music that was common, movies that pertain to situation, familiar areas, "using clothes", hardware rar etc...
any thoughts that come that you dont want, there is no need to entertain for long, take time and find a way to disassemble these thoughts as tricks, tricks that you are playing on yourself. there is a very good reason you want to stop, and that easily is forgotten amongst all the cluster that stuff finally leaving your mind brings.
what was very helpful for me finally, honestly, was feeling crazy giving people my money to do for themselves, while i was manipulating for others money, only to do worse for and to myself, over and over.
and the realization that, i was going to die a rotten death this way, and disgrace my body mind and soul the whole while.
my goal, that i pinned over when i was released was to bang as much as possible, and then smash my .... in a _ _ _ car, immediately.
that was 15 years ago, im very glad that thought is only a memory i very rarely feel even comfortable mentioning as an , honest "goal" for my life.
its way gone now though, and im not.
so such powerful thoughts, need only be written about at their very best in a creative manner, expressed as fictional angst.
