woke-up wide awake, not sure why its 2am

I'm sipping lots of water and i seem to have no problems with it passing thru. My blood sugar is high ????210.. it could be from the meds they gave me in the iv? I'm not sure what to call the feeling i have.. it feels like i'm just real sore in my upper gut. They told be they used a larger band due to the size of my stomach?
anyone know anything about that?
