Its worth asking. Kai and myself don't have the symptoms except I am a fairly anxious person but I have come up as borderline and Kai has it. It is genetic though. Some of the basic symptoms fomr memory are: anxiety, depressionm, panic attacks, mood swings, sensitivity to drugs and medications, all day brain fog, poor dream recall, ridges and white spots on nails, family history or alcoholism or mental health issues.
Oh yes, Zinc takes months to build up... did you get your copper tested too since both are hand in hand, if the copper is high is must be actively brought down at the same time as increasing the zinc.
