My puppy. First thing at 0430, get up, take him out to pee, get dressed, go for a short walk, inside for training (all kibble is used to training), then hand him over to my wife at 0530. That hour really gets me going, but only because I want to give the puppy three best life, which also brings me joy!
Go to bed early the two nights before, if it's just a one off thing. If I'm adjusting my schedule I'll take some NyQuil or melatonin to help sleep only the first two nights or so.
You can't make yourself sleep. You can make yourself get up. Force yourself to get up early the going to bed early part will take care of itself.
Oh and you should stop drinking liquids a couple of hours before bed. Unless your a man over 50, in that case if you want to sleep through the night you'll have to avoid any fluids after Tuesday.
One of those sunrise alarm clocks, going to bed more than 8 hours before it goes off, a neti pot or benadryl so I can breath while sleeping. Blackout shades, and an air filter that makes some soft white noise.
