The trills! They tickle my face so bad!  I can't finish the exercise and then my face is itchy for a long time after.  Will this go away?

They do tickle at first! The tickle eventually went away for me, but if it's unbearable for you, feel free to use any other semi-closed exercise (like singing through a straw, NG, VV, ZZ, etc). It also helps to sing a deep, rich UH underneath and leave space between your back teeth (so the mouth has more space internally, even though the lips are still closed at the front). Hope that helps!
