Are you increasing your water intake when you do? That sounds like dehydration. Creatine takes a large amount of water to appropriately process, and during the loading phase, your body is pushing substantially more water into your muscles. Anecdotally, if I don't drink something like an extra half gallon of water a day while loading at 15g/day, I show symptoms of dehydration. And I'm already drinking somewhere between a half gallon to a gallon a day.

I think I do but I guess I could try.

Something to add to the spreadsheet :)

Yes I can definitely “feel” it when I take it, especially so at 10g+. And it makes me overly reactive and somewhat irritable, and gives me a ton of energy that needs to be let out lest the former two get worse.

What does this mean?

They likely keep a journal of their mental state in a spreadsheet? Generally a good idea

I keep a spreadsheet about my health, blood work, any supplements I take, how they make me feel etc. The summary would be that I take zero supplements now haha. I have tried so so many.

Any chance you'd be willing to share a template of your spreadsheet?
