for heroin it's ... hard to describe? one thing about heroin though is it is motivating as hell, at least in terms of motivation to _obtain heroin_ and you're going to do stuff that ranges from ill advised to ... very ill advised? anyway, thing i discovered is that if you stop taking the stuff, it takes a long time to find a replacement motivation. e.g. found myself waking up, discovering i didn't have an immediate need for heroin, and then, well that's it. nothing important to do here. it was ... annoying? fucking terrible? still is, so there's that.

Good way of putting it. It’s in the chest for sure. I’ve always thought of it as something missing in your chest - a type of emptiness. “Thirst” is a good metaphor.
