I get night sweats and as yet have never done a cycle. I don't use creatine very often but the severity of these sweats increased when I started supplementing in general althought I have suffered to some degree my whole adult life.
I would love to know what is causing it, I've read many articles that suggest it could be to do with consuming more kcal that your body needs and your body quite literally burns these kcal causing you to over heat and sweat, I'm assuming this only really applies if you have an extremely high metabolism (I've never been able to put on weight I was 57kg from the age of 16 to 26 and only by eating 4000kcal a day have I now at 29 managed to get to 70kg.) I have seen no scientific support for this though.
I regularly wake 2-3 times in the night and need to change my clothes, it tends to be even worse if I sleep naked, which I assume is because there is no fabric to soak up the sweat.
I find it slightly hopeful that some people here have had reduced symptoms since cycling maybe I have a natural hormone imbalance? I will see when I'm finally ready for my first cycle in a few months time.
