I had my gall bladder removed many years ago, the "old" way before laser surgery. Actually, I had double major surgery...removal of my gall bladder and a total hysterectomy at the same time. I remember being uncomfortable from the gall bladder incision for about 24-48 hours, and being a little nauseous. Actually, the worst part was that the nurse brought me an extra pillow to hold on my abdomen during the
required coughing therapy. I don't remember exactly what that was about, but that was the first day while I was still in bed. The nurse did not seem to think I put enough
gusto into my cough

and would proceed to instruct me on a proper cough.
After that, it wasn't so bad. And the whole thing was
no where near as bad as the gall bladder attacks I had been having for years before they diagnosed what the problem was!
You'll be okay whichever procedure they use, and will feel so much better afterwards!!!
