Jasmine out of control

I am not sure what took place while I was in Australia, but I arrived home to a jasmine plant that had grown wild. Usually my jasmine plants bloom few half-hearted times and then give up to a bout of spider mites in the most unheroic manner. But this plant is growing faster than it can keep up with itself. In fact, its arms(?) are so gangly and out of proportion to its body, that I had to enlist the aid of some kitchen skewers, a chopstick and some bakery string for the plant's own good.
