Crazy habits

I finished piecing a custom quilt that I have made for a customer and now it's time to mount it on the longarm table and start another level of creating.  When I finished sewing I realized that I had chewed my inside of lip so bad that I had created a swollen bump inside my mouth. So I relaxed a bit and went back to my next steps and realized half way through that I was still clamped on the inside of my lip. What is this all about? I feel like a canible that's eating themselves.  This is crazy.  Does anybody else have trouble relaxing when you are in creation mode or is it just me?
