Like Jopet says; don't be too sure about the nipples not being puffy.
Mine were perfect until 2 weeks post op. Don't want to dissapoint you but you need to realize that there is a chance that they will come back (even though the glands are gone). If all goes well they will become flatter in the months after that. Might take a full year even...
Scar tissue is a bitch, and it takes time to heal completely.
OT: take it easy the first weeks. I had surgery July8th and I only started feeling comfortable enough to work out etc. 6 weeks post op. 10 days after the op (like you), I wasn't even thinking of doing anything that required energy or lots of movement.
Take care!
