Stock up on some Gatoraide and hydration liquids and get a lot of ice. Right after my RARP Ice water felt better on my stomach. You will also want to get some higher fiber foods, so that you won't be straining. Also stock up on some foods that you can easily heat up like soup. I had a slight change in my taste right after surgery and everything tasted different. That took a few days to resolve. You might want to get some Protein drinks like Ensure etc. I lost about 5 pounds after surgery.
