Don't try to stop taking the drug all at once. You will need medical help to get you through a gradual withdrawal period. Tell your doctor exactly how much of the drug you have been taking. Also tell your doctor if you are taking any other medications. Don't hesitate to be honest.
Doctors are familiar with the problem.
Support-group meetings and counseling can help you quit. Take advantage of both. Eat a healthy diet, drink 6 to 8 glasses of water a day, and get plenty of rest. Don't smoke or drink coffee or alcohol. They can make you nervous and increase your withdrawal symptoms.
