Okay so that was Vicodin you just took, not oxy. It's got 10mg of hydrocodone (the good stuff) in it, 10-15 is usually a normal recreational dose for a first-timer. Since you've drank expect it to hit you at least twice as hard as that, so you'll probably be nodding pretty hard later on. If you start to puke, idk what to tell you, make sure you don't lay down or you take the risk of falling asleep, puking in your sleep, and choking on your own puke. Don't take any more or you could risk liver damage and/or overdose.
