That depends! I was sleeved in August (down 50 lbs). I was worried about all kinds of things. Were they going to use a catheter? Were they going to shave me? How much time will I have to take off work? Jeez, am I ever glad all that is behind me! BTW- no catheter, shaved from waist to nipples. Went back to very light duty after 5 days.
What's really next is trying to get in all your water, protein, exercise, vitamins, and other "rest of your life" things. Also what's next is enjoying your new life. Good luck!
