It's weird, I have a different experience generally...for me heroin seems to be mainly a psychological addiction. The whole thing about "WAKE UP DOPE SICK, NEED HEROIN NOW! Text dealer, drive into the ghetto to cop", I don't get that...I've gone through WD a couple times but it's always surprised me when I realize that I'm in WD because it doesn't happen often. Also, I don't need to go anywhere to get heroin. It would come to me.
But, despite being primarily "mind driven", it is still a very real compulsion and when the idea of going out and getting high initiates in my head, it's nearly impossible to stop. You have to nip that shit in the bud really fast, because once it reaches a state of critical mass it's just about impossible to resist. The thing about heroin which really bothers me is that it's so tempting to use when you're sad or depressed...it doesn't always start out as that but it usually becomes that, or so it seems to me. What started out as a fun bit of recreation becomes a coping mechanism and it's not good when that transformation starts. You realize that it has begun to sink its claws in you.
But yeah, the constant, brutal war-of-attrition to prevent being dopesick? Of constantly being on the hunt for heroin just to feel normal and not be an incapacitated, puking, sweating mess? No, I can't relate to that. At least not yet
