Healthy living is more than just weight control and nutrition. There are many damaging substances and behaviors you must guard against from abusing drugs and alcohol to road rage. As such, the anxiety that you may feel as a dieter is not limited to food consumption. These same feelings may be felt and amplified if you try to stop drinking, smoking, taking drugs or even limiting caffeine and driving safely. It will be tough and often physically uncomfortable to eliminate bad habits. You must be tough. There are patches and pills and counseling sessions to help, but in the final analysis, the breaking of long-term, negative habits will require your inner resolve to be successful.
