Good. food allergies are just the tip of allergy manifestations though. The fungus was killed in your liver, allowing it to be more functional--less food allergies .
But the allergy could be in your liver where you can't see it. Keep looking. There's something, I bet, which will cause you to think the zapping's failed. And again (and again) what are you expecting the zapper to do? And what will be the indicators of success or failure??
Losing weight and toxins and burdening your liver isn't a good idea now really. Your liver's already struggling, why would burdening it further be helpful???
