I've been sipping my 1 oz of water every 15 minutes but, I get to a point were I am full how long should this last? I'm still quite thirty.

Same my mouth is so dry but i know if i take one more sip i will vomit. Really frustrating.

I found this the first two or three days after surgery but 8 days out and it’s a lot better. Perhaps try sipping on something with electrolytes? I drank coconut water (pure, no sugar etc) for the first few days and it really helped.
