Has anyone had Top Surgery?

Hi all! I’m agender and have a surgery date to get a double mastectomy/Top Surgery in 6 weeks. I’m insanely excited as I’ve loathed my chest my entire life.

I’ve been doing (a bit too much) research on what to expect/tips/tricks/etc and found many people had a rough time hormonal for a few months after.

Has anyone else had top surgery? What was your experience? Any advice?
