I too am having a laparscopy on Nov 6th. I have had one before to have my gallbladder out and it really was not bad at all. I barely had any pain, did not get sick from the anesthesia. I don't think you will have a catheter either or if you do, they will take it out before you wake up. Are you having it outpatient?
The Ga may make you sick it verys each person. I get bad motion sickness and nausea so I ask for a scopalamein patch (probably spelt wrong) but its amazing. I felt bad the first day after and then felt good. Good luck
