... forgot to say... a problem my coach identified with me was I wasn't being patient enough with my leading hand as I turned to breathe. In turn my breathe was hurried and I was lifting up my head. Focus on keeping that hand out in front as you turn to breathe so your 'laser beam' remains straight and it feels nice and balanced. You could try something like catch-up drill or the TI skate drill. The superman glide is good too.
Maybe: superman glide a few times to find that sense of balance, then skate drill turning effortlessly to breathe (its an exaggerated over-rotation but should feel balanced and easy). Once you feel alright with that do a few repeats of a catch-up style drill being patient with that lead hand.
