1000mgs of Hydrocodone would most certainly kill you.
Vicodin and generics contain hydrocodone (opioid) and acetaminophen (tylenol), they come in 5/500 7.5/750 and 10/660 Hydrocodone/Acetaminophen. Im assuming you have the 5/500s, two of which would be 10mg of hydrocodone...that wont do much. Try 20-25mg, four 5mg pills.

If you don't know which kind you have post the pill imprint on here and i'll tell you.
