Look, before the smoke gets so harsh you are on the floor crying swearing you'll never smoke again, it will go from smooth, to tickling your throat a bit, to kinda hot on the throat, to really bad, to death, try to stop it at step one by moving the coals around. if moving the coals around doesnt work, try moving and taking one off, if that won't do it, you probably are done. after a while you will get used to knowing how long your session will last given your hookah setup and tobacco.
