Alcohol rehab and drug rehab are designed to treat the root causes of your addiction and challenge and change the maladaptive thinking processes that drive compulsive behaviours. Rehab can definitely be a life-changing and life-saving process. During the rehab process, you will undergo intensive therapy to unearth and treat the root causes of your particular addiction. With the alcohol or drugs safely removed from your system with medical detox, you will look better and feel better and be able to think more clearly. However, it is important to remember that addiction won't disappear overnight. You must use all of your recovery tools learned whilst in rehab and apply them to your daily life to maintain remaining well and abstinent. On leaving rehab treatment, it is normal to feel a mixture of fear and excitement. Fear due to the fact that you will have learned the seriousness of the addiction and excitement due to returning back home to your family and loved ones. You may leave under the illusion that you are now able to deal with cravings easily. However, leaving the supportive environment of the rehab means finding the strength to continue recovery alone. Complacency and overconfidence are often what leads to relapse.
