The ibuprofen bottle says not to take more than 6 per 24 hours unless directed by a doctor.
Oops. I've been taking about 10. Then again, those directions are probably for someone half my size. My dentist told me once after having a wisdom tooth removed to take two every four hours, and then two ace... aceta... Tylenol every four hours between ibuprofen doses. So, I'm sure I won't die. I think I'd be pretty happy dealing with whatever non-coma side effects there might be from a slight overdose of ibuprofen when compared to the screaming pain in my ears if I don't. You know, unless my heart stops. That would suck.
