My feeling is that problems have to be a problem :-) If you can afford 82 bottles of nail polish (or pairs of shoes) and that's what you want, what's the difference between that and 82 books (like I have :-)

I could get into trouble though, being late for work, because I was reading. That's a problem. If you get to work hung over from drinking the night before or don't get enough sleep and "crash" on weekends, etc. that's a problem. But it doesn't necessarily need treatment unless you can't fix the problem alone or get fired and/or someone else is supporting you and has an issue with your buying all that stuff.
