I've told my family, friends, and boss. When I started the process I told a few close co workers that I was thinking about it and got their unwanted opinions. I just said "the doctor and I both agree that this will be a positive thing in my life an thank you for the unsolicited advice." I want people to know rather than worry about the drastic changes in my life, but I don't want to hear how it didn't work for someone they knew.
