Get tired with korean soap opera, but...

I am really tired about myself going through korean soap operas one by one. But it seems to be impossible to quit this bad habit. Sometimes I even don't know what is going on about the soap opera, simply making it as a background. I can really do a lot of things while watching them, such as writing a paper or browsing web pages. And every time a soap opera ends, I try to push myself not to choose another one. But I fail every time. I don't know whether it is really a bad thing because things won't be delayed due to that. But it is really bothering me, too. What should I do??
