hi, the coating on your tongue most probably is from the acid reflux, also could be a fungal infection, keep away from sweets and cut down on your sugar intake, are you taking proton pump inhibitor medication? if you are, then your dose should be 40mg, one at night and one in the morning for about two weeks. then back down to one a day, also you should be tested for fructose malabsorption, lactose and glucose intolerance-they are simple breath tests, and gluten intolerance-this is a blood test. let me know how you go, cheers.
