Nothing you have described sounds to me like OCD or addiction, just some obsession with instant gratification...and I have in days past had that same problem. Money seemed to me to fall from trees when I was young and I never learned to handle it prudently, so it was quite logical that I eventually spent it foolishly, frivolously and even lazily while trying to attain/maintain a sense of satisfaction and leisure comfort.

Breaking your bad spending habits will not be easy, but it can be done by setting goals (possibly in conjunction with one or more other people) and denying yourself the cheap thrills of days past.
