Alright, so, since I'm an impatient fool, I took 3 ibuprofen at around 4 PM and apparently thought that waiting another half hour for them to kick in was ridiculous, so I took 3 more at around 4:35 PM. My stomach began to twist in knots and I just figured it was a stomach ache (I get a lot of those), but then I began to have diarrhea not long after. Any help with what I should do?
