Is it true ingesting visine will give you the 'runs' ?
It used to, the ingredient that was responsable for causing "the runs" has been removed since the late 90's. I think they got wise to the old bartender trick used on non-tippers.
Probably but I wouldn't test it, that sounds miserable and people are suffering enough without having gut wrenching painful stomach afflictions.
i think so. And its really hard on your kidneys as well.
Read the possible side-effects on the label. If it can cause diarrhea, it will be on there.
