you may have a nightshade issue and you may have a fructose malabsorption issue. i'm not a doctor, nor do i play one on the interwebs.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
