I am 4 days out and the thing that was a game changer for me was stopping the narcotics. They were making me extremely exhausted but agitated so that I would feel the need to get up and pace every hour. I am allowed up to 3000 mg of Tylenol per day if needed. This is my second day off the narcs and I haven't needed anything. Today I just felt so much more normal and with it, and was able to do the walking on my schedule without having to take multiple naps.
Obviously if you are still having pain, this won't be a solution for you, but I thought I'd throw it out there.
Also, on Surgery Day and Day 1 I was extremely nauseated (and actually almost threw up my barium swallow, which was a real treat). They finally got me on Compazine which controlled the nausea. I had to take it the first couple days home but now I'm ok. So if you aren't on a nausea med, ask for one asap!
I was totally regretting my decision on surgery day and day one out! But once I started to feel more normal and was able to have a full night's sleep, my attitude got much more positive.
