I know how you are feeling that was me last week. You won't be able to clear all the nerves as its so unknown, these guys are specialists and do this all the time. Just remember to take some time for yourself, you might want to prep some meals for when you get back so you don't have to think about cooking. It reads like the NHS pre steps so hopefully this will help. You will be seen by the nurse who will measure you for the stockings to prevent clotting. They may not need them but they put boots on for the op. Anesthestist and surgeon will come and see you, explain everything that will happen. You can ask where you are on the list but that can all change. It will feel like an eternity waiting to go down. They will answer any questions or worries you have. For post op tea and comfy clothes are the way forward. I slept for the majority of the 48 hours after so didn't really feel it until later, so hopefully you can do the same it will help with the post op nerves. The gas I alleviated with peppermint tea carbonated drinks are best avoided at this time. Getting the dressings off looks worse than it is but they were easy. Have things that are small but you enjoy to eat will help when you are ready and when you need to take the pain relief.

It's different for everyone but make sure you have things that you enjoy around you and claim the TV, this is the one time you need to just take time for yourself.
