It goes away imo and the longer you stay off it you can actually develop a loathing for the drug.
If you talk to people with lots of time clean they might tell you they still think about their DOC, but a lot of them speak with disdain towards it. Also happens in break ups. After a month the person is a mess and wants their lover back regardless of the price.
After 6 months they still think about them, but reassociate a lot of their virtues as faults.
After 2 years, maybe they still cross their mind once a day, but the gap that time creates will tend to fill up with a lot of facts/reality/negative bs rather than rose tinted fantasies about something that never existed (like thinking we actually liked our lives on drugs).
Fastforward even more time, say 10 years, and a total unforgiving hate can wash out a lot of the memories.
Or if hate is too strong a word, maybe finally just accepting regret for past decisions.
For me, a year of meth I still thought about getting high, the rush, being in a state of paranoid euphoria, I told myself I still liked it and would go back one day.
After 2-3 years, it no longer felt right thinking of something that way that realisitically destroyed an essential part of my life (teen years/early college).
Now, almost 11 years later. I have a hate for meth that is relentless and consistent. No more bouncing back and forth between love/hate like in the initial years off it. I rarely if ever think about it anymore only usually if I'm reading posts on here. And there is not even the slightest bit of love left for it anymore. Once that love is dead, truely dead, there is no way around it imo.
I can look at meth, meth labs, meth pipes, ephedrine, matches, iodine, engine starter fluid (ether), all the things that use to trigger a desire to use, now trigger a hate that is likely one of the deepest hates I have for anything in this world.
From how immense and powerful the cravings use to be, that have done a complete and total 180 in the other direction over the years. It DOES happen. You just need to really not use that drug at all. I never relapsed on meth after I quit, and if I did after 2-3 years, who knows what my perception of it would be like now? Maybe I would still get cravings. But I had hit a rock bottom that was so low and disgusting, there was just no way for a relapse to happen. Even when I got intense cravings in the begining, there was always this surreal type of awareness that there was NO WAY in hell that craving would be acted upon.
It was a TKO. The end. I knew it. Cravings DO go away. And that is something I guarantee you. I'm sure in the 6 months you haven't IVd, you're seeing that pattern of dissassociation to some degree. But also realize 6 months is nothing in addiction time. It likely took me 7 or 8 years before I felt strong in the face of speed. But when that happened, I realized there was no way in the world I would ever go back. And I can tell you with 100% certainty today, its one drug I will never use again. I don't miss it anymore. Its dead to me. And so is the person that drug created.
But that doesn't mean I'm cured of my addiction. I'm cured of my addiction to speed, but I'm still eligible to succumb to addictions to drugs that don't trigger that hate. Like opiates. It became my new love. And I genuinely hope I don't need to reach that same type of low before I realize I can live w/out it. Thats why I'm trying to walk away now, I'm trying my best, but opiates really are a different animal altogether.
Point being, if you've made it 6 months. Try really fucking hard not to relapse. There is NEVER "one time". We used every day, traded our lives and loved ones, gfs, jobs, anything we had to keep using. I guarantee it will not be one time. You haven't been away from it long enough. Really consider that. And goodluck man. It DOES get easier, I think that part is honestly inevitable.
