In brief: Not advisable
The usual dosing of afrin for an adult is 2 sprays/nostril twice a day.
Any more is overdosing. It does not give incrementally improved results and risks you complications like headache, insomnia and nervousness. Absolute maximum time of usage of afrin is 5 days. Longer than this leads to tachphylaxis and worsening of nasal congestion. If you find yourself chronically congested, see your doctor.

Using Afrin (oxymetazoline) more than once every 10 to 12 hours (twice a day) for 3 day (5 days max) can cause significant side effects.
