The patch is for nausea and you can wear it for three days..BIG help..felt nauseated but haven't thrown up so far.. I did not stay overnight, it was my decision but I had a 10 year at home sick and my husband couldn't be 2 places at once so I chose to come home. It has been a rough road, worse than I had expected but Im probably gonna live..Can't get my 60 g of protein in and am really struggling to get my 64 ounces fluid. I guess right now is the frustration period.My throat and mouth hurt from the tubes..my stomach hurts from the incisions., cant get comfortable and the headaches are horrible..Quit the caffeine as soon as you can to help with this:cursing:
