Too much or too little sleep?

I laid down earlier to get just a few minutes nap. Ended up sleeping for several hours. I'm very inclined to just go back to sleep for the rest of the night, but I suppose I really should get up and get some work done instead.

I had told my friend that during the two weeks she was not around to chat with I was going to finish the novel I had been working on - have not even opened the novel program yet.

I'm not sure if I am getting too much sleep, or too little sleep.
