    MOSAIC Rule Change

    If your AHI was 10 then you had sleep apnea. I would suggest getting another sleep study, but if you are overweight you should lose weight before the study. You might also want to see an ENT surgeon first to see if you have a surgically correctable cause of upper airway obstruction.

    Best wood Spitfire replica drawings?
