How can I wean off mental health medications?

"wean" is right. Most medications have some effects when they are discontinued, especially if they are done suddenly. Benzodiazepines, seizure medications (used in psychiatry as mood stabilizers), certain blood pressure medications (used in children who have adhd and behavioral and sleep issues, and some adults with anxiety and panic), and some antidepressants, all nead careful withdrawal. Your dr. Can guide you.
With your docs help. One should never try to do this based on something you read or an on-line response. Whatever individual prescribed a particular mental health medication, for a particular condition and particular medical history should be consulted so one can learn your specific risks and the particular way to do it. If they are not available another competent psychiatrist or physician should be seen for consult.
