Good luck to you! I just had surgery 4 weeks ago and would like to offer this advice: prep your pantry with a wide variety of things you might need for the first 2 weeks. Buy the smallest quantity you can. Your taste buds may change, so you won't know what will taste good to you. Also, you sense of smell may also be enhanced. Mine sure was. Hated having any scented lotions and hair products on me.
Also, get up and get moving as quickly as you are able after surgery, even in the hospital! It has made all the difference in the world to me. I went to Zumba class last night. I was pretty tired after, but feel great today!
