I am currently thinking on a character addicted to some nasty stimulant like meth. What I consider one of my few talents in the area of writing is being able to empathize completely with things like mental illness and addiction; I can really get in these peoples' heads. My problem is that this character should be nothing like me and I'm having trouble giving him any depth. He's a scumbag-- a manipulative moocher-- a real jerk. but surely there's more to him than that, right? He's a person, he needs his next fix sure, but what's he do when he's not looking to use? What did he do all the time before he was addicted to drugs? I'm just having this bizarre problem of seeing him more like this plot device serving a function than being a person (a bad thing for a writer to do in my opinion). Could you guys give me a few pointers on how to grant this character a little texture and still be the amoral addict he needs to be to move the plot along? PS: I am not now, nor have I ever been a drug addict (unless you count caffeine). My name is more of a joke than anything.
