I posted in another thread that I had a weird sleep schedule going on. I'd basically wake up, have a snack, drink some water, use the restroom, do some sort of activity until I got tired again, and sleep for a few hours. Wake up and repeat, for the entire week. At night sometimes I'd sleep longer. I was probably awake for up to 5 hours at a time at most. It worked out great.
I had a few different things around for when I was awake. I did play a lot of video games. I made it through a few seasons of a TV show. I read two books on my Kindle. Played around online, Skyped with long distance friends.
I also broke the rules and walked my dog. I have a waist leash, so no stress on my arms/shoulders/chest but I could see how it might be too much for some people. Personally, I think it was good to get up and out of the house at least a little bit. Even if you have somebody there taking care of you, try to get up and walk around the house as much as you can. You will feel much better in the long run.
