Nap?

My leg is recovering swiftly. Time passed swiftly too. Now, i started to hate taking a nap. It's nice to has a nap. But everytime i do so, it will be hours. At least an hour or 2 hours. When i wake up, i will say oh my gosh, overslept. Then, i will not be able to finish my works within the day. Just slept for 2 hours just now again. OMG.
