Where have all my creative juices gone off to?

When I first came onto Y!A, I would marvel at my own genius with all the fab answers I gave. Now I'm feeling like I can't muster up anything even mildly entertaining. I fear my contacts will start boycotting me. My brain feels mushy. Does lack of contribute to lameness on Y!A? If I get some action, will my answers get back some of their lost luster? Am I getting stupider because my are bigger now?
