Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain slimy feeling inside the mouth when there is no coating present along with a history of having recurring Candidal infection or
thrush can be due to thickening of saliva due to reduced serous[ watery] component of saliva or it can be due to an inflammatory condition in mouth known as
Burning Mouth syndrome that can be causing Oral Sensory Neuropathy which leads to transfer of abnormal impulses to brain and appearing to feel that is not exactly present..
Although it is an irritating condition but does not seems to be anything fatal or life threatening so you can first of all relax over it..
You can stop using the mouthwash that you seems to be considering a culprit for the problem..
You can do warm saline gargles..
Gargle with specialized mouthwash formulated for
dry mouth patients like
Biotene..
Chew sugarfree chewing gums and tart candies..
Take Vitamin B complex suplements..
In case if do not find improvement in 2 weeks time consult an Oral Physician and get evaluated and he can do a clinical evaluation and look for causes..
You might be referred to a neurophysician to get checked for
nerve related problems..
Hope this information helps..
Thanks and regards.
