well ... I think I have figured out the problem.. I belive it is called" thrush" .. it tastes bad .. and is an annoying fungal infection of the mouth.. ruining my pipe smoking and such.. So I am thinking as a protective measure I will try to disinfect my pipes.. as this thrush buisness started when I started to smoke my pipe this season.. I am a seasonal smoker .. I dont tend to smoke in hot weather as I have not been able to stomach it in the past. now I know it's just the start to my mouth falling off .. ha ha .. but I am wondering if any of you ever had a simular issue? how did you treat it? I have some "pipemasters clean and cure " so I think I will see if that will kill those fungal bad guys .. at that end anyway. and for the other I will get me some listerene. Also I will make some "switchel" ..." switchel" for those that don't know, is an old time hay makers beverage that is made with apple cider vinigar, molasses, ginger and water ... there are many variations both in name and contents but these are the basics..
