Not an AC...

The oldest get home from work late. The house is hot so little kids wake up every five minutes then they get up early... But that would not even matter because my son needs a ride to Football early too... So short nights with many interruptions.

A new mattress is on the "list" but not in the cards for a while. Ours is 15ish years old and was a cheap one sided one to begin with... So that also doesn't help.

The Swamp cooler issue is only a problem in the summer... But I do sleep better in the winter.

Thinking about that... Some blackout curtains would probably also help...

So... To answer your question, I bet a CPAP would not hurt... But it I one of many factors at play...
