oh that's so great that you use a pendulum!!! :) I use kinesiology myself, and yes it IS tough to use it for supplements/foods guidance at times. But I've seen people use the pendulum to great effect for wonderful guidance.
Some candida people do fine wtih a bit of unsulphured molasses or brown rice syrup or even grade B maple syrup as their sweetener. So long as you don't overdo it should be fine. :) The complete no-sugar rule should be in effect for at least a month, but after than a teaspoon or tablespoon a day shouldn't exacerbate yeast too much.
