My sleep level varies with the amount I workout. When I exercise regularly, I sleep 5-6 hours most days with a quick 20 minute power nap in the afternoon. When I don't, I sleep a few hours more. Both figures are how much sleep I get without an alarm. When I don't exercise regularly, I set the alarm for ~7 hours later and wake up groggy for 30 minutes or so.
