I would start with just the zz and see how you do.
Definately be prepared for some pain. Be prepared, but dont neccesarily expect it, because it seems sometimes in mild cases, some peoples infestation doesnt cause much of a healing crisis from thousands of dying mites. Some people just get better immediately (lucky bastards!) ;)
My face is so terrible. But people have told me, every time one pops up, just think "yes! Another nasty bug is dead!"..that mentality helps.
