It starts with an almost unconscious feeling that all is not right with the world.
It is a sense of impending doom that lasts for maybe a second or two.
Then it hits.
There is the gagging reflex, with a sense of nausea that is worse than the worst hangover. The eyes stream and the throat feels raw. Everything takes on a sickly green hue. There is a strong urge to vomit which I resist as best I can. The dizziness is the worst, as the blood drains from my head, leaving me feeling cold and clammy.
All I can do is sit tight and wait for it all to pass, which it eventually does after what seems like an age.
Jayzus, but that dog’s farts are lethal.
