Have already done a search on the site for this, but nothing has really answered my query.

For the last couple of nights I've suffered from excruciating leg cramps (plus I've been feeling very tired). I already take magnesium (400mg), calcium (1000mg) and potassium (99mg) on a daily basis.

Should I increase this? or am I perhaps missing something else?

Any thoughts etc., would be appreciated.
