i think and asked my Nero, Do i bite my mouth because of the loss of muscle? Yes , he said. It is falling inward and so my teeth bite it. Mostly in the night. It does keep getting worse and worse...darn it! Now sometimes I will turn my head in the direction of the part that I am bitting so it falls outward and not inward.. So many fun strange things going on with our bodies? Hugs to you today. Linda
