<s>[INST] Hi, I have very bad white coated tongue. I am also suffering from constipation and have mild hypothyroid. Are they all related? is there a cure for the coated tongue? is there natural suppliment for these problems? I take 0.010mg syntheroid every morning. I am suffering for many years now. Please help!
