I'm in my mid-thirties, & I have slept alot my whole life. Even after sleeping 10-12 hours at night, I can still take a nap (weekends). I sometimes feel like I just can't get enough rest. I don't have any health problems that could be contributing to this. My family & friends pick on me for sleeping so much, but I can't help it. Is it normal to be able to sleep this much.
