I had the same issue with sleep apnea, which also affects your memory and ability to concentrate. Because I was already operating at an extremely high level, I went from one of the top of my field to above average -- but still quite good, so on the surface, when I tried to get jaw surgery for correcting my small airway, people looked at me like I was crazy. I ended up getting it anyways, and now I feel my health recovering to the point where it was at before. Skeptics are even noticing the difference, too.
