I too, like @Summerabbacat, am inflicted with allergies not typically troublesome elsewhere. Although I occasionally have the same symptoms writing my own stories. Does GA emit some pheromone that affects certain users in this way? It must.
Anyway, sad to see it (almost) end, but look forward to reading more from you, once I slow down my own writing to one story at a time. Although I am working on a third, just not publishing it yet (not making THAT mistake again - two is more than plenty). Oddly enough, that new one doesn't cause that allergy. You really make the characters come alive and we care about them. Well done, sir.
