how do you know if you're addicted to pain killers?
A state of addiction is reached when people habitually or obsessively surrender themselves to a substance or behavior. A person with an addiction uses a substance or behavior to escape from pain or reality. Yet by the nature of addiction, they only hurt themselves or others, and continue to deepen their addiction.
Well the simple answer would be, taking them when you dont need them... Or needing a higher dose to get high. Or taking them regularly... Or taking them to cope/deal with whatever...
Try to stop taking them.
