Mostly though, I'd just read some books on what the various nutrients do, and then guess at it and try things out. Maybe add a lot of magnesium for a week, 2-3 tables
a day of 100%RDA each. (RDA is probably an american thing from the FDA regulations, so maybe look at a site like Puritans Pride to figure out how much is a daily dose here?) If that does nothing, then try calcium. Also, a short stint with valium muscle relaxants might break the cycles and let it heal more.
