Breast Reduction!

Breah • 20, Pro-Black, Muslim, buzz cut.
I got approved for my breast reduction and I should be having it in either February or March. 
I'm so excited. I'm a DD, trying to drop down to a B.
I've had my consultation with the surgeon, he's a military surgeon - and he is very knowledgeable. He's the only plastic surgeon on my base, so the entire thing will take close to 5 hours. Yikes! 
Has anyone had this surgery?
Any tips? Especially for scarring?
