No, I have never learned how to do biofeedback, but I have heard wonderful things about it, and it's great in conjunction with psychotherapy. Some therapists do teach their clients how to do it. I would like to learn how to do it for myself. I do progressive muscle relaxation, visualization, and breathing with my clients, though.
Had a CYPHER stent January 5, 2004 after a heart attack. Diagnosed with CAD and CHF. Need to care more about myself and do my exercises, lose weight and eat better. Still the happy grandmother of 4 beautiful grandchildren!
