I feel your pain! I had surgery on 9/8 as well and my energy is definitely not where it used to be. Even though my energy isn't there, I make myself exercise every day (except Sunday, that's my break day). I've been walking an hour, which is 3 miles a day. Even though it's a chore, make yourself do it. Once I do it, I do feel energized. I also can't do the protein shakes any longer, so I've been eating foods rich in protein. I'm thinking the lack of energy will go away when I can eat normal food again!
