is lack of sodium my problem?

Strangest thing!

Last night I went to bed and as usual my body decided to start hurting, twitching, send bolts of lightening through my muscles, etc.

Well, last night it was quite bad. The "twitching" sometimes feels like little bugs crawling around on me and even under my skin. Like RLS where you have to move to "shake" it off. It was so bad I couldn't even sit still.

Then, the thought of popcorn came into my head. Now keep in mind it's around 11:30pm-midnight and before all this twitching, I had slept for approx 20 minutes.

Couldn't stop thinking of popcorn, with butter and salt. I don't eat popcorn as a rule!

Got out of bed, fixed popcorn, crawled back in bed, ate way too much of it with quite a bit of Celtic sea salt and hmmm...my twitching stopped. I slept through the night more soundly then I have in weeks.

Is low sodium my problem here (or at least one of many?)

any advice truly appreciated!
