How on earth do you manage to keep your tongue firmly pressed against the back palate and around your back molars?
After 1-2 seconds of doing this my throat gets really sore (like a muscle strain) and the suction loosens up.
Also, are we meant to hold this position 24/7 (aside from eating and talking) or is just having the tongue touching the palate (without pressure) suitable until the suction right before a swallow?
