I was also wet
I was inside a house when I took the antibiotics
I took a stack of six antibiotic pills (each usage consumed two pills)
The antibiotics were inside my pants when being used
Playing on a persistence server
The antibiotics were damaged but not ruined
I also took charcoal tabs and nothing happened.
Someone suggested I make my character vomit as it cured their sickness from eating a worm, I will report back if that works.
