If you have any problems with anesthesia you should let it be known 1-2 weeks prior to surgery. Then the meeting with the anesthesiologist is basically a meet and greet. The first surgery I had (5 years ago) had anesthesia much too strong for me. I made notes and shared them for the next time. The next two surgeries were much easier in that way - they even gave me a patch to help with any nausea. It was a miraculous change!
