1St post op post

Hello, 1st post-op post Good Moring ! Hope everyone is doing well. I am 5 days out, And I had to be opened, This has been the hardest thing so far. Please tell me it will get better, I know it has over the last couple days. My questions is when will I be able to sleep for more than an 1hr-1-1/2 at a time. And I am soooo sore when I move, I have been non stop walking, trying to get things moving, I also feel like I need to go to the bathroom(#2) and cant- I have taking milk of magnisiam to see if it will work. Any up lifiting thoughts would be Great Thanks ! Melisa
