What helps for me was using cool/chilled water, and a swimmer's nose clip to help reduce the smell of the ingredients. If you are adding flavor drops - go with lemon and not anything blue or red in color.

One other piece of advice - stay off the internet afterwards until you're sure the anesthesia has worn off. My doctor related that a previous patient had gone on the Carvana website and bought a car while still under the effects. Oops.
