Finding out that my insomnia issue may be related to creatine?

I'm not sure if it's related yet, but I've been going down a rabbit hole in this subreddit of what could be causing my insomnia issues. I've been dealing with this issue for roughly 6 months, though I feel I've been taking creatine for longer than that. I did, however, move to 10mg of creatine every morning.

It never even crossed my mind that the two could be related. I always chalked it up to sleep anxiety ever since I got back from an international trip and was severely jet lagged (screwed my sleep up for a week and it just snowballed from there).

I went on vacation last week and didn't have any creatine and slept pretty well, though could be just that I was less stressed on vacation.

The anecdotal stories in this subreddit are TOO common to ignore though. I'm going to quit cold turkey today for a couple weeks and see what happens.

Am I on the right path or am I crazy?
