I hope I'm not leading you astray, but I would follow my own advice without a concern.
I shouldn't pass up a chance to end the year with a sea story. This should make you feel safe and/or make you sure that I'm dumb.
In 1967 I flew an RF-4B from SoCal to Vietnam, with one night stops in Hawaii, Wake, Guam, and the Philippines. On each island I managed to get in a scuba dive in the afternoon, a couple as deep as 100 feet, and then launched early the next morning. When the F-4 is cruising up in the 30,000 feet plus range, the cabin altitude is around 17,000 to 18,000 feet, more than twice as high as in commercial airliners. Of course that means that the pilot has to wear an oxygen mask, but most of us just let the mask dangle from one side of our helmets so that we could talk on the radio until we were about to take off, and then we would fasten the other side and breath pure oxygen. Since I was in technical violation of regulations concerning flying after diving, I was putting on the mask as soon as I got in the cockpit. I suppose it was usually about 20 minutes from start to takeoff. Since the partial pressure of nitrogen in the gas I was breathing was zero, this accelerated the off-gassing of nitrogen in my tissue, reducing the chance of bends. What I'm not sure about is how much the breathing of oxygen helped, and of course you won't are able to breath oxygen anyway. But since my situation was more extreme than your's, going from scuba dives to 18,000 feet the next morning, I doubt that oxygen totally offset it.
This probably didn't help a bit, but at least I got to tell a New Years Eve sea story from back when my life was exciting.
