Should I avoid drinking any water or keep it minimal the day of my Juvederm lip filler appointment to add another ML?

should I avoid drinking any water or keep it minimal the day of my juvaderm lip filler appointment to add another ML? Like will me drinking water before I go into the appointment make my lips look bigger than they truly are which will make the injector think I don’t need more. To avoid this should I just drink minimal water so the fillers don’t swell before the appointment?
