Huh? To actually think that taking 6 extra strength pills in 24 hours isn't enough margin of error? I mean maybe if the person is completely clueless and doesn't read the medicine instructions.
Honestly, if you're in that much pain that you're gobbling up 6-8 extra strength pills per day, every day, you should be in the hospital with an IV hooked up, or addressing the chronic pain issue that's causing it. Or have the doc prescribe you something way stronger.
