I know the feeling. In my case, I've been able to put off doing much book-buying by focusing on the amount of unread fanfic lurking on my Kindle (though occasionally there are sales and I find myself stocking up while it's cheap, like the Patrick O'Brian spree a month or so back) -- but it becomes a source of minor stress, thinking about all that stuff waiting to be read that I don't have time to get to, and having too many weekends where I'm too busy to lie around reading for hours on a Saturday afternoon... (Or, too many at-home hours that could be spent on reading, but I feel obligated to clear things off the DVR, or knit something too complicated to do while reading. And the Olympics are starting tonight, which is going to pretty much eat any at-home reading time I would have gotten for the next couple of weeks...)
