Sleeping in

I knew that I was kinda tired, due to fighting a cold, but I've gotten more than 12 hours of sleep two nights in the last week. Last night, for example, I got a whopping fourteen hours of rest. Tonight, I plan on leaving myself enough time for about ten hours of sleep, but I hope that I'm getting over whatever illness is leaving me so tired. Needing this much sleep is rather worrisome. :(
