Lack of sleep and lack of water

I woke up this morning absolutely exhausted.  I got 8 hours of sleep, which for me is 2 (sometimes 3) hours more than I usually get.  I assumed since I woke up so tired that I must not have slept well, but my wife thinks otherwise.  Apparently our 5 month old woke up at 11:30, 1:30, 3:30, and 5:30 to nurse (in our bed) and I didn't even move (yes I was still breathing...).  So what I thought was poor sleep appears to actually be an accumulation of not enough sleep.  I thought I was being so good, but my eyelids and body say otherwise.

On top of that, it appears I have a hard time drinking enough fluids at home.  When I'm at the office, I don't have a problem - every 2 hours I'm up getting another glass of water.  I don't know why it's different at home.

So, I've taken today off, and likely tomorrow too, from any training to try and get my muscles some rest.  I can't guarantee enough sleep until Saturday, but it'll have to do.  Oh, and I'm getting up right now to get a glass of water.
