Just started Zoloft and Buspar, so far the only side effect that's bothering me is loss of interest/motivation. Any way to combat this?

I've been on antidepressants before and this was also a problem. Even playing video games or watching tv shows doesn't hold my interest for more than 15 minutes. I'm not in a really bad mood or anything, but all I want to do is smoke cigarettes and stare into space.

It's my weekend right now so I'm trying not to feel like I'm wasting it. I'm not looking to clean my entire house or anything, but I'd at least like to play some video games or something that resembles a form of entertainment. Has anyone else experienced this that knows how to counteract it?
