Yes, I enjoy books where the main character gets addicted to something other then a woman
Where you're reading their train of thought and it really creeps you out.
I'd prefer something realistic but not necessarily a true story.

I've read -

Double or nothing - Dennis foon (on gambling)

Tweak by nic sheff(i think that's the author..) - It's Non fiction, so not sure if you'd read it. But i thought it was a great book!

Crank Series, i've heard good reviews on it. Everyone who's read em that i've talked to has liked them, but i have yet to read them myself.
Crank (Crank, #1), Glass (Crank, #2), Fallout (Crank, #3) By Eleen Hopkins.

Both drug addiction.

Idk any for gambling, good luck with them!

A Scanner Darkly.

Phillip K. Dick is EXACTLY the author you're looking for.

I, as you, love that creepy bizarre feeling these kinds of things. Can't stand normal movies/books

idk if you've ever heard of brandon novak, he's a skateboarder, has been on viva la bam, jackass, etc. but he wrote a book (nonfiction) about his life. its called dreamseller and its about his addiction to heroin. it was surprisingly good.
