Tristan the Fidget Puppy seems (at approximately 18 months of age) to have abruptly worked out a way to fidget every twenty minutes all night, but without getting up and moving across the bed, under the bed, across the room, and so on. He is staying mostly on our pillows, occasionally between us or at our feet, and when he needs to fidget, he only rolls over or stretches or shifts his position on the pillows.

Puppy has become a consistent night skull snuggler and human cuddler.

I would wonder if it had anything to do with the long vet visit last week and the antibiotics (either helping, or making him feel sick and needy)--except he suddenly started the extra cuddles the night BEFORE that vet visit.
