At this point I am just waiting to try and get voice back. It has been completely gone for over a week. My pulmonary dr is trying to get me in at UAB with dr that specializes in MAC so will probably not start anything till I see him. Have you had anyone who tried the Arkayce and lost their voice who did not get it back? Getting sorta concerned. My husband may enjoy the peace and quiet but even he is getting ready for some noise from me!
