That's Zofran, good stuff. It is the gold-standard in anti-nausea med, although by the time you took it , it might have been too late - the train had already left the station.
wb - my wife had an episode like that once - we were caught in a late-spring snowstorm in Bryce Canyon. Kept moving, climbed out, but after getting back to the Lodge for 6 hrs she shivered and was cold despite hot shower, food, and blankets. This perhaps is analogous to febrile illness where there is shivering when the body tries to RAISE its temperature, ( but sweating when the body tries to LOWER its temperature)
Coldest I ever was was after Aconcagua. Plenty of subzero F nights, but I handled that okay, but back at the trailhead, chugging 3 Cokes in rapid succession was like having an ice enema. I imagine that.
