I couldn't find the thread where we discussed whether it was okay to skip one night of therapy. There was a lot of hysterical fretting that you might die or worse! I didn't have Cpap for most of my life (and I'm pretty sure I needed it) and I managed to survive so I don't really subscribe to that camp.
So having said that, I went on an overnight camping trip with my boyscout troop and I thought "I'll just leave the cpap at home this time." (I have a battery that I've used with good results a number of times but it's a hassle and it's tough to hear the crickets and frogs over the machine!)
Big mistake!
I woke up the next morning with a horrendous headache and a raw throat! Never mind the boys thought a bear or something wandered through camp that night!
So no it didn't kill me but I won't do it again. As much of a hassle as it is, it's not worth losing sleep over!
