I was taking this med and Glucophage and experiencing bad breath with extreme dry mouth. My husband said it had the smell of my teeth being infected, but this was not the issue. I originally was on two pills a day, 25 mg and didn't seem to have the same problem as when I started the Diethylpropion SR 75mg. I got off the diethylpropion and it has gotten better. I was just wondering if anyone else had experienced this?
