Vic,  This sometimes is a symptome of a mineral deficiency specifically
calcium and/or magnesium.  Are you getting plenty of these?  If that is the
case, you have not been on this diet long enough for the diet to have caused
it.  More likely it was coming on before you changed your eating pattern.

Hope that helps,

Ann
