Sippingly

Because there is nothing sottish about you; and you throw down your wine like a man that wants to get a certain quantity down in order to drown care, and not like one who drinks it because he likes the taste of it,—that is, slowly and sippingly.

I have long observed, as I doubt not have many of you, that the condition here described is often alleviated in the most striking manner by the use of exclusively liquid nourishment—such as milk or milk-gruel, given in small portions sub-continuously, or sippingly, as it were, throughout the waking hours—the patient being never permitted to take a distinct meal, nor a particle of solid food.

He might ignore it for three months and then, one midnight, drink sippingly and methodically from a water glass, lying back on the cot an hour later with the world all closed down, nothing left of it but a terminal throbbing ache in his forebrain.
