My tongue has this hair-like texture and I don't know how to get rid of it.

I've had this "hairy" coating on my tongue for nearly 1 year now, along with gastro issues (diarrhea, loose stools, etc) and extremely dry mouth (despite having normal blood sugar (diabetes) and negative Sjogrens antibodies.

I test negative for candida overgrowth and using a tongue scraper usually helps with removing the bacteria on the surface, until it appears again in the next morning.

I smoke and drink coffee, so currently trying to reduce those and see it helps.

I also recently found out i have reactivated EBV, so my gut feeling tells me it's something related to it.

Can someone possibly help?

Many thanks.
