The mouth-tapers aren’t always wrong (though we do always look silly).

Kinesio tape seems to be the solution

You need a dose high enough to penetrate the blood-brain barrier, around 0.3g/kg (so ~30g for a 100kg person).

I've also heard just practicing circular breathing by blowing through a straw into a cup of water can produce the same effect but playing a didge is just so much cooler.

But seriously, yeah pretty much, usually with some beeswax on one end.

I haven't read into it much but I believe the circular breathing excercises strengthen some of the muscles that tend to relax during sleep so they keep your airway open.

So as long as you’re trying things, CBT is the most evidence-based long-term solution for the (very likely) cause of your insomnia.

It might have some kind of neuroprotective effect. For people who are already very healthy, there may be no measurable difference. But for the rest of us, it may be more helpful.

I'm reminded of something I read about dual n-back. (I forget where, it might have been Gwern page on it.) Someone said that when they are sleep deprived, they feel totally fine, but their n-back score absolutely tanks.

It might be interesting to test that, the intersection of sleep deprivation, creatine and objective measures of executive function. That could give us more data on the "helps most in stressed cases" theory.
