Sam , I too would be looking elsewhere as this is a long road we are traveling and to me , trust in the competence of your doctor plays a big roll in the process....No one (patient or caregiver) deserves to be treated in the manner you stated . I would take advice from people in your area and go from there . As far as the liver levels go make sure you have a base line liver function test and then be tested as required (I get blood work every 6 months) . Best of luck , and hope your husband finds relief soon . Take care !
