Of note:

I was going a good job with my cannula. I kept an eye on my pulse ox, things were going well.

Started eating some trail mix for lunch.... oh yeah, mouth breathing. Pulse Ox was headed south in a hurry.

Just something to think about. I had to be extra vigilant to not stuff my face all at once, and when taking time to drink and eat... consciously make sure to take good hits off the O2 with my nose.
