Hello, I m Craig from St. Catharines, ON, Canada. I ve been fighting off some form of the flu, my family doctor prescribed for me Penicillin and this did not do a thing. I have had this microbe or whatever it is since mid December. It has all but gone, then it came back again and again, I ve lost my voice twice and people tell me they can still hear it when I talk, I m nasally congested, my throat is a bit inflamed and I am purging mucous. A neighbour mentioned that an antibiotic with sulphur will clean you right out. I welcome your advice...PLEASE?
