There definitely should have been better information for you before the procedure, I'm not sure where the fault for that lies. For instance, my surgeon has an approx 2 hr class given by the bariatric nurse coordinator on the day of your pre-op tests. All the patients having the surgery the same day as you attend together, unless they make other arrangements, but attending the class is mandatory. In the class they go over everything that will happen & what you can expect to feel etc from the minute you check in for your surgery. I have to say she was right on the mark about the whole 24-28hrs I spent at the hospital!
