Too much sleep OR Not enough sleep?

Michael and I have noticed that being married is QUITE a bit different than being single. One of these major differences is what we do at night. Since we no longer have a social life other than each other of course:), and don't have to worry about staying up as late as we can together to prolong our goodnight goodbyes, our bodies have decided that they would like to sleep. Now, Michael and I don't just sleep the normal 5-6 hours a night a normal college student does...we sleep at least 8-10 and sometimes even 12 hours a night! We have found that the past month everytime we get to our apartment we immediately start feeling tired. We are wide a wake throughout the day, even in some of our boring long classes...but for some reason the second we step in our apartment and decided to cuddle for a few minutes we both end up fast asleep. At first we thought we were overly tired and trying to recuperate from our wedding and honeymoon, however now we think we might be getting too much sleep! On Tuesday night we got home from school at around 6:30. We ate dinner and then went to cuddle for a few minutes before we started our homework. Well within minutes we both were fast asleep and did not wake up until 7:30 am! We still don't know what is wrong with us....:) But I think we will just enjoy our evenings of cuddling and sleeping together for as long as we can.
