I’m new to the forum. I started picking up cigar smoking about a month ago. I really enjoy it. I brush my teeth and rinse my mouth out with listerine daily. However, I have noticed recently that I have what seems to be a constant sourness, a sour taste, in my mouth. More pronounced in the morning when I wake up and occasionally through the course of the day. The only thing I have done different is started smoking cigars. Wondered if anybody else has had this and what can be done about it? Thanks for your help
