Call it the coffee conundrum: What to do when new sugary drink rules come between a harried, half-awake New Yorker and a morning cup?

Come Tuesday, when Mayor Michael R. Bloomberg’s ban on the sale of large sugary drinks goes into effect after months of public debate over the measure, its impact on beverages like soda will be clear: no more jumbo colas. But coffee drinkers, and those who pour them, are likely to face a thicket of complications as varied as the lattes, macchiatos and Americanos on a Starbucks menu.

Customers at Dunkin’ Donuts and McDonald’s can expect to add their own sugar packets and flavor swirls to large and larger coffees.

At other cafes, some will be given one lump, or perhaps two, in their coffees; those seeking more will need to visit the condiment stand.
