Hi, Renee. I would suggest:
Searching or browsing through the forums for items to take to the hospital and things you might need when you get home.
*hint: a search of the phrase "abdominal binder" will get you the quickest results.
Try several protein drinks/shakes to find what you like best. And pick a few up for your first few days of liquid diet. Only a few. You need less than you think AND your taste buds may change post op. But you do want to have a few things handy.
Buy a small package of unflavored protein to add to soups or warm beverages.
Keep practicing your new, healthy habits. They are what are going to give you long term success.
Welcome to the group and good luck.
