R.B.
A friend of mine (incidentally also named H. :) !!) had this done a few years back and she was pretty well fine within a week or 2, at the most. But like others have said here, have a plan B just in case you're not feeling up to the travel. Everyone is different and responds differently to medical procedures like this.
Blessings to you and I hope this takes care of your endometriosis issues!!
