Quietest days are Tuesdays and Thursdays and some early morning slots are available (for text and internet only) from 8.00am on Mon, Tues, Thurs and Fri. Occassionally, due to exceptionally high levels of demand, the clinic may need to close before the times indicated above. However all patients will be assessed on clinical need by a triage nurse and offered a walk-in slot for the next day.
