Look, the major bummer of quitting coke is realising that all your friends are boring and you yourself are also boring. And you need to find something to do with your time other than go to clubs and do coke. And suddenly you remember you get hungry. You get bored and arsey for a bit. That's fucking it.
It's more that it completely burns your serotonin receptors, while increasing the actual level of serotonin in your bloodstream. The result is that when you quit after a long time, not only are your serotonin receptors completely blown out, but they're also used to highly elevated levels of serotonin, which you don't have any more.
Since most pleasure is mediated by the interaction of the neurotransmitter and its receptors, the result is that for months and years, it is basically impossible to enjoy anything at all, something called anhedonia. And even the dumbest cokehead knows that all they need to do to turn the fun back on is some more cocaine.
It makes it even more insidious than heroin, where if you ride out the puking and shitting part of the withdrawal like it was a bad flu, and maybe fix some of the shit you fucked up during your addiction, you're probably okay. Well, except for the gnawing, eternal knowledge you could get rid of whatever pain led you do that addiction in the first place, with just a little push.
They're both absolutely horrible drugs that do absolutely horrible things to your life, your mind, and your actual physical brain as well. Did I mention your soul? Drugs are bad, mmmkay? Not sure how we ended up in an argument about which ones of the absolute worst category are worse.
Oh, yeah,
@Dyn. Thanks for that btw.
