I take vicodin every once in a while, I don't have a prescription for it so it's hard for me to get, the last time i stole from a friend, i'm really ashamed of this but i just wanted to get high so bad. So I guess I was just wondering how do you know if you're addicted or not? and when does it become a problem? So far it hasn't really interfered with my day to day life, I just do it when i'm feeling low.
