Unmarked Events and Periodic Flow Rate Spikes

Before I use a bleep, I wipe down the whole area it will stick to w/ an alcohol wipe to remove skin oil. 

Here's some different examples of Bleeps failing mid-night on me.   I'd roughly guess that about 75% of the nights I've tried using a Bleep, something like this happens at some point.  25% of the time, the seal sticks all night.

Couple more Bleep mid-process fail examples

I also use the Bleep mask, and I also wipe the area with an alcohol wipe. I then blot with a kleenex before applying the ports. I also cut the ends off the ports and use them as buttressing pieces on the outer sides of my nares. That's the area that, for me, would be most likely to fail. Do you have a sense of where the Bleep fails you?

Also, do you notice moisture as a culprit in loosening the adhesive seal? If so, you might try lowering your humidity setting and/or raising the tube temperature (if you have a heated tube).
