Welcome. I think nerves are quite normal before surgery. I think I was so desperate I had kind of made peace with it, but I'm not really normal. I never took anything for pain, but that's me. You will be given pain meds and try to stay ahead of the pain especially at first. Protein powder or ready made shakes are a must. You will not be able to meet your protein or water requirements at first, but it is a goal to work toward. Stay hydrated. This is really important so you will be sipping all day. Every surgeon has there own plan and you should have been given instructions on what and how much to eat at different stages. Your sleeve will be healing so don't overfill. I think I tried yogurt first and then a scrambled egg. I could only eat 1/4 at first and then gradually worked up to more each time. I know it sounds strange to have to chew an egg, but you have to really chew. It really sounds like you are preparing and this is a great indication of your commitment. Wishing you a speedy recovery. Stay connected support is crucial.
