For my pct I just play it by ear.  I keep letro, exemestane and nolvadex on hand and use it according to how my body feels.
Did I mention my wife is now pregnant?  Woo hoo, I still got it!
CPAP machine works awesome.  I sleep almost the whole night now, No snoring, no stopping breathing.  It isn't all that bad, I get used to the mask the first night, was rather natural.  Besides, I like breathing more than my looks when I am sleeping.
