Check out different strengths of Vicodin, there are actually some with low acetaminophen levels and high hydrocodone levels, those are the ones you want. They are 10/325 (in other words 10mg hydrocodone and 325mg acetaminophen). Regular Vicodin are 5/500 which is asking for an OD on acetaminophen. Just check what kind you are getting and you'll get plenty fucked. I'm considering buying some myself, and I've been researching a bit. The 10/325's are def the way to go.
