laparoscopy(endometriosis)

Hiya, I’m having my first laparoscopy week after next. It’s to make sure that I have Endo which I’m 99.9% that I have because I had bad period since I was 11. I miss school because of my periods and was practically bed ridden for a whole week while running back and forth to the bathroom. Anyway I just want to ask what should I do while getting ready for the surgery, I know no food for 48 hours and that’s gonna be hard. And I wanna know you guys experience with your laparoscopy.
