Definitely! I would not recommend it to make up for lack of sleep for extended periods of time.

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

I suspect creatine is responsible for me not being able to get back to sleep easily, because once I'm awake, I'm awake.
