How not to get an advise from a friend after venting to just get it outside my system?

I don't complain about life all the time, but when I do I always get serious advices and solutions from my friends whom I'm complaining to. Even though I'm open to suggestions, most of the time it gets annoying and I feel like I'm obligated to follow their suggestions. How to vent without getting miserable advices and/or solutions?
