Just an update on Dads treatment,He is 3 weeks in and 3 and 1/2 to go. He has mouh sores,burnt skin,constipation,nausea and just cant eat. He says he feels as though his throat is closing up.Does anyone know if that is normal?God he still has 3 plus weeks to go!!!! We were wondering also about something called colloidal silver as a gargle and mouth wash, has any one heard if this works?
