Put some whisky in its milk?! Lol!! Joking apart, it certainly should of settled in by that age. I agree, give it a bollocking and only let it out for a pee once its quiet. As with kids it has to learn that there are ways of asking for the same thing that get different responses.....please may i go out gets a yes ok and hyper yapping gets a smack on the nose and a shout of shut up! And as watchman sais, plenty of exersize, preferably just before bedtime.
