If your magnesium is off so can your potassium.

Actually, good dark chocolate is a pretty good source of magnesium .. when I was pregnant with my kiddoes, I wish someone had told me that. My chocolate cravings made me put on a bunch of weight! All along I was magnesium deficient.
Having said that, there are better sources of magnesium ... nuts and seeds, dark greens -- look it up. And if you end up supplementing, don;t use magnesium oxide. There are more available sources.
I'd get tested first though -- the blood test isn't that accurate but if you are deficient with the blood test you are REALLY deficient. A magnesium load test is more accurate. Also make sure you are getting enough calcium -- honestly, I wish I had known when I was your age that a lousy diet would cause so many issues at my age.
Do what you can now :).
Oh! I didn't know magnesium level causes this. Maybe it's because I haven't eaten any nutritious foods and eat only candy and chocolate these days...
Thanks for the help :D!
I haven't had large, visible fasciculations in ages -- I do still twitch, especially after exercise, but it's minor and ignorable :).
It might be a good idea to get your magnesium level checked to see if this could be an issue for you.
