Going back to the bedside?

After two years at the bedside, I accepted a management position. I was sure it was what I wanted to do, but after 6 months I am feeling the desire to go back to the bedside. I'm a little concerned about how my manager will react when I tell her this and was wondering how you other managers would feel. Have any of you had an experience like this? Is 6 months too soon to leave my current position?

I appreciate any advice you can all give me.
