Good luck!

Stock up on household supplies
Get an Amazon prime membership and have anything you need during recovery shipped to your front door
Work on abs, lower abs to help you get out of beds, etc. since you can't use your arm to assist - if recommended by your dr. Or pt of course.
If you are a woman someone recommended a strapless bra, bandi, since you can't lift your arm over your head.
Wash your sheets and bedding before you go.
Eat healthy, like super healthy!
Again, if you are a woman, and also have long hair, put hair in tight ponytail on the very top of your head, braid it, wrap it around in a bun, don't wash it until you can or have to!
Dry shampoo adult cleansing cloths.

Anybody else?
