Can't Sleep

I'm sure it's common at the end of pregnancy...but I sure haven't been sleeping well lately. Between the baby's weight pressing on my ribs every way that I lay, and the fact that I'm always getting up to use the bathroom....it seems that I only get about 4-5 hours of sleep a night. I know that in a way this is probably good and helping to prepare me for when the baby arrives. It's just hard because then I feel kind of yucky the next day. I'm trying to take it easy and rest up as much as I can, because I know that I will need my energy here in the next week.
