I know that surgery is no cakewalk but sounds like there is a good chance something positive will come out of this. It's great that Alan can have you at his side to get thru it.

Regarding anesthesia, I have problems with being too sensitive to it. It doesn't take much to put me out and away and when it is outpatient, I have a hard time waking up so I can go home. So from some of the other posts with other people having the opposite problem sounds like we are all different (no surprise). Since Alan has had surgery before, IMO it's good to use that as a benchmark which I think you are doing.

Good luck and very best wishes.
