I am 1 week out also.
I have severe pain & nausea when I drink plain water. I can drink anything else fine. So getting enough fluids has been so hard.
I totally understand the "sip,sip,sip" not working I want a huge drink to quench my thirst.
I could not take my antibotics crushed, it made me throw up. Finally called my regular doctor and she prescribed me some liquid. Much better!
