Weak and tired
I am just over a month since my surgery, I was exhausted for the first two weeks after. I just wanted to sleep all the time. Just this week have I felt some of my energy coming back. But I have noticed that doing little things does tired me out. Went swimming this weekend at a friends house and I was yawning all the way home like I ran a marathon. The energy does come back. Give it time.
People kept reminding me that it takes a couple weeks for the anesthesia to get completely out of your system. I had many friends who had completely different surgeries that struggled with it. You have to slowly get your stamina back. Don't stop trying, but be patient with yourself. I found that after the first 5 days that I would have energy about every other day. I think I'd be active (relatively speaking) one day, and then need the next day to recover!
