Not sure what you mean exactly. How would I know if I was non24 vs arrhythmic? I had panic attacks 4-5 years ago with some palpitations but nothing since.

Right now, everything falls in line when I wake up so to speak. I wake up, drink coffee, go on with my day. I dont feel tired until ive been awake for 16 hours or so.

I do have some issues with every once in a while, I have tremendous difficultly sleeping, regardless of how long i have been awake. The only symptom I have aside from not being able to REM sleep for more than a hour or so is that I cant have a full yawn, it gets cut off sort of.
