I hope all goes well. I definitely have to agree with the ladies here. When I had lat flap surgery with expanders I was in the hospital for 4 days. I was 32 and otherwise healthy and it really threw me for a loop. I don't say this to scare you, I just think you should be realistic about the recovery time so you are not disappointed when it doesn't seem fast enough.
I hope all goes smoothly and you are back on your feet in no time.
Do not go gentle into that goodnight,
Rage, rage against the dying of the light.
