I know where you are coming from! WE are all so different..my theory about sensitive people is that apart from anything else they may have inherant weak adrenal function, which makes all the difference to recovering from any form of stress ..so even too much excitement can make an adrenally weak person feel overwhelmed..
So your husband probably is quite yang with good strong adrenal function..
I did not realise at first the the Medifolan..is that right, is actually a form of special seaweed..I like the sound of this product and will look into it.
