1. A method of dispensing a medicine from a wearable medicine dispensing device, comprising:
- rotating a battery-powered, reversible motor housed in wearable medicine dispensing device according to a motor rotation cycle that includes one or more full rotations of the reversible motor in a first rotational direction and one or more full rotations of the reversible motor in a second reverse rotational direction, wherein the rotation of the battery-powered, reversible motor according to said motor rotation cycle urges a drive mechanism housed in the wearable medicine dispensing device to advance a piston rod in a longitudinally forward increment toward a medicine in a reservoir arranged in the wearable medicine dispenser device; and
dispensing at least a portion of the medicine out of said reservoir arranged in the wearable medicine dispenser device in response to movement of the piston rod in said longitudinally forward increment.
