I'm so sorry the first few days were hard on you. I'm happy that the worst is past now, though.
I was lucky to come through the surgery very easily. At my first post op doc visit, they were all amazed at how well I was getting around. I'm not bragging, I'm just trying to say that I think I must have been the exception and what you experienced is probably more common.
I was banded on March 24th.
