Mind that, while the "creatine high dose to fight drowsiness" hack works and has no side effects (other than upset stomachs), the lost sleep still does it thing. You don't notice day to day but it will catch up to you eventually in many bad ways.
One of the things I'm trying to do better lately is to have a good sleep hygiene. Sun in the eyes early in the morning, no caffeine for the first 60 waking minutes of the day (adenosine absorption period), no screens 2 hours before bed and whatnot. Still, some nights I will just wake up in the middle of the night and won't be able to get back to sleep, then it's when I feel creatine helps
Edit: Typo
Also @ others in this thread.
I'm eating 10g, in the morning, don't have tendency for stomach issues, taking it mostly to have more energy at a physical job.
I can definitely run longer on it before being tired, but not sure what to observe for other effects?
I suspect creatine is responsible for me not being able to get back to sleep easily, because once I'm awake, I'm awake.
