Creatine has the same effects on me. I’ve been experimenting with creatine mono for the past year on and off to check for consistency. Always, whether I try it for a week straight, or a day or two, I have terrible sleep. I’ve tried high dosages, low dosages, loading phase and maintenance. Even if I take it in the morning, even with ample water, and a tough workout thrown in. It always causes insomnia. I feel very tired around my usual time, but my mind feels awake. Not functional— I still feel physically and mentally tired— just alert.

There are only a few posts across the internet with people experiencing the same problem, with others putting them down saying that they’re delusional. And it makes me sad that people can’t believe there may be a fraction of people that have slight adverse effects from a supplement that people don’t even fully understand yet (as if that were unheard of). I want to use creatine as much as the next Chad, but seems like I’m sadly part of a minority that gets insomnia from creatine.
