thats probably right. i have no experience with that because i spent a decade detoxing. the only thing i have had a hint of lately was mercry and that was because ii was stupid enough to eat some tuna a couple of times.
plus, i have been supplementing the missing minerals. more than blood type, i think the problem is always being poisoned and deficient. that acconts for the great variety of symptoms and difficulty - mixing and matching different degrees of toxins and deficiencies.
