I check in to hospital tonight for the second round. Last time I was there to prove that I "apnea" at night -- stop breathing while sleeping. Tonight is to be fitted for a CPAP machine -- a device which should prevent the apneas. This procedure is completely without ill-effects or risks, and yet I've had a growing apprehension and anxiety over it. I don't know why. It will be over tomorrow. And my life will be insignificantly but measurably different.
