I’m not a machine at all, I just think I am 
and at times act like I am …well when I’m not being a shitty prick which was about 3x in the past week. :mad:
Firstly waking at those real early times isn’t by choice and is not something I enjoy, it is stress related due to all the things I have to sort out. I have a 30 minute relaxation audio that I set up beside my bed so if I do wake up I listen to that which helps as otherwise my mind races which drains me. Listening to the audio and even dozing afterwards helps.
Secondly I am usually asleep between 10.15-10.30 so waking at 5.45 ish is 7-7 1/2 hours which isn’t out of the ordinary. Being up after 11pm really knocks me. I went for a period of about 18 months a few years ago where I averaged about 5 1/2 hours, :o that was when I set up the not up before 5.30am rule.
Wednesday (3.20am) was fine, Thursday (4.20) I felt great and that was after I had done work at home from around 9-10.30pm the night before.
Generally I take pretty good care of myself which helps too and I don’t crash and burn so much. I was quite tired last night (Friday) though but I had a good 7 hours sleep (helps as I sorted heaps out at work Thursday & Friday) and will chill a bit today so expect to firing on all cylinders tomorrow 
I have always been a morning person and when I was younger and playing competitive golf would routinely play 36 hole in a day tournaments on 6 hours sleep without any issues.
Planning post season just about complete and major thanks to Boldwarrior!
