Either way, I don't have the same symptoms as they are experiencing.
I suppose I could stop "spiking" their drinking water for a couple of days and see if their symptoms subside.
Interesting experiment though, don't you think?
Then there's the ethical question of giving them something that they have not consented to. However, I used to have to hide vegetable in the spaghetti bolognase to get my kids to eat them, so I don't really see the difference.
