What's up with that?

I really wish I could figure out why, on my nights off, I can't stay awake anymore. I used to have no problem. I'd come home from work, sleep all day, get up and eat dinner, then be up all night knitting and watching movies. I just can't do it anymore. I'll get up by 5 or 6, then by 11:30 or midnight, I'm completely zonked and fall asleep on the couch! Then I have to try to sleep most of the day too so I can be awake at work that night.

Maybe I just need to catch up on my sleep this weekend. Oh wait! I won't be able to do that because I'm picking up a poodle puppy for my mom on Friday morning and she's probably going to want to go out every couple of hours. Lovely.
