hi ravi,
good luck this week. i hope you can get as much relaxation as possible rather than work up a worry cloud for the next few days til surgery day.
someone mentioned eating very mushy foods and i would probably add soups mostly and liquid stuff rather than solids until surgery day and a few days post. it will help keep your bms smaller or at least more manageable through the before and after.
give yourself and your body time to heal and don't build up expectations at all. just know that you will heal and be on your way to a happy butt.
prayers on the way.....
