Anybody here throwing around dosages in the hundreds of milligrams doesn't know what they are talking about. Perhaps you're confusing the amount of acetaminophen with the amount of hydrocodone, which comes in 10mg at best.
If the pills are 5/500 hydrocodone/acetaminophen then it seems to me $5 a pill would be a total rip off. You will most likely need more than one maybe even four though you don't appear to have an opioid tolerance.
