diarrhoea only affects the pill if it is 5/6+ trips of FULLY LIQUID. it’s nothing to do with how long it’s been since you took your pill, that rule only applied for throwing up. as long as you didn’t have fully liquid diarrhoea more than 5/6 times in that hour and a half you’ve stated you had it for then there was no need to take a second pill. you never lost protection, i’ll attach a link surrounding sickness and diarrheoa if i can find it x
