Drug addiction is a real problem for people and anyone who is hooked on painkillers or other drugs will tell you that it is very difficult to get off of them. This is because the detox symptoms are so nasty and make people feel so sick and ill that they feel forced to go back to using the drug again. It is the cycle of addiction and the onset of withdrawal is what keeps people trapped.
So the best way to get through the process of drug detox is to check into a rehab center. There they can give you medications that can help with the detox symptoms and help you to stay a bit more comfortable. You will still experience some discomfort but it will be nowhere near as bad as if you were detoxing cold turkey.
