@lileitak This is my 2nd lap this year and I have severe endo. You wont feel a thing, you will be put to sleep and wake up feeling dazed. If this is your first surgery which I think it is, wear something like a loose smock dress and very loose underwear in case there is a cut where your pubic line is- go buy this if you have to, it will help you get dressed and make you feel a lot better than having to pull up pants. You will need to go straight home to bed so I just sleep in the smock dress.
I would also buy some large water proof bandages at the chemist as I use them for at least a week or so each time I shower post op to keep my wounds dry. The wounds a very small incisions. I don't know how many you will have. I have 4 but that is also once again my endo and depends on what Dr needs to do. I feel like I am a rather 'complex case' so my surgeries will always be a bit more in depth.
When I lie flat I am fine. I don't take strong pain killers, just panadol. To be honest fasting is probably one of the worse things.
People get lap surgery for all sorts of things, but because we are for reproductive reasons the nurse told me to be super careful post op, don't over do it at home with any chores or lifting anything over 1kg and rush to get back to work as they want us to heal properly.
Let me know how you go!
