Dry Pleasure
The act of squeezing out any remnant pleasure from an activity, as a part of one's daily routine feels like something I would call "dry" pleasure. The activity can be mundane (is mundane according to the rest of the population) yet feels "right at home".
Drinking water is extremely pleasure at best, and "I don't mind" at worst. Reading a book/article/essay, for the sake of completion/habit, some form of work and other things can be seen as dry pleasure depending on what one's preferences are.
Though an exception (not strictly definitionally) would be reel doomscrolling. It has an instant feedback mechanism that isn't "dry" enough, and while some pleasure is derived, it feels or is more like an addiction.
