get symmetrical 

When inhaling powdered drugs into the nasal passages, getting symmetrical means to use both nostrils to inhale the drug. It is common practice to alternate between the two nostrils, so that one doesn't become asymmetrical, which is the opposite of the desired effect.

Let's get symmetrical this evening in the VIP room at the discotheque.
