I was just sleeved on May 15th in Mexico. I stayed 2 nights in the hospital and 2 additional nights at a nearby hotel. I did really well and although I think I could have gone home after one night I think having an extra day of IV fluids was helpful. I was walking 2 miles on day 5 post op and I have had no problems getting my fluids in.
Honestly, this is major surgery and I just don't think I would have been comfortable going home the same day.
