Several times now I've had trouble falling asleep due to a weird spasm feeling, almost like tightening and relaxing at the same time, mostly in my low back. It's not achy or painful, it just feels like it wants to relax all the way and almost is about to, but kind of remains tense. It feels almost like waves.

I don't know if this makes any sense, but it's a weird feeling I've had several times lately and it prevents me from sleeping. It happened last night and I took a magnesium supplement yesterday for the first time in awhile. Now I'm wondering if the other times it happened I had taken a supplement. I know for sure when I was taking the magnesium regularly I didn't have this problem.

I could experiment with this more and possibly figure it out, but I wondered if anyone on here knows what I'm talking about or the cause.

p.s. I've been so-so with the paleo lately and pretty much end up on here with "weird" issues or questions when I've not been as clean. Then I recommit more after getting some answers, so thanks.
