Avoid Blistex products. They have analgesics in them that irritated my chap lips to no end.....as for the dry mouth..not sure. Do you have dry crack commisures, the corners of your mouth???....If that is the case and they feel like they may be burning, you might have angular chelitis and need some anti-fungal and anti-bacterial medicine, usually 1% iodoquinol with 1% hydrocortosone. You will need a Rx for that one though...good luck, I know how you feel man....
