Call your PCP and ask for a scrip for a nausea patch that goes behind your ear ASAP. sleep in the recliner or propped up, go ahead and take all the naps you need. Try some Protein Soups instead of sweet shakes, sip some ginger tea.
DO NOT take the load of crap from the surgeon's office, ask for the office manager if they keep this up, everyone has a boss. There is no reason to not get the care you need. I would show up and puke on their floor...
