Most people that go through rehab have a relapse but not all. If it does happen stay positive and keep using the tools they teach you. The enviroment shes around has alot to do with it.When she gets home you have to keep the old crowd away even if you have to get mean and run people off.My mother went through rehab in 94-95 for pain med addiction and it had to get bad before she wanted her life back.She has been clean since.She told her old friends not to come around anymore.She was on pain meds all my youth and high school years.High school was rough with her but shes been clean and I am proud of her!
