I've had the same problem at first, but I'm getting better now. Instead of buying books I put them on my wishlist, like I used to do at Amazon. It's like making a note that I might want to buy them later. With p-books I found that if I bought too many at the same time, often some of them would end up gathering dust on my shelves, and if I didn't read them soon after buying them, I might not read them at all. I think it's the same for ebooks. Buying a book (or downloading it for free) is a pleasure in itself, because of the anticipation. I try not to buy/download too many at the same time, so that I can have that pleasure more often
