I get severely congested only at night and the only thing that helps is afrin (oxymetazoline) which can only be used for 3 days and the cold 60 and under. cause?

Humidifier: If youre using a heater, you might need a humidifier at night to moisten your mucosa. Otherwise you can ask you doctor if he can prescribe you a nasal corticosteroids such as Flonase combined with an antihistamine like allegra. If you dont suffer from heart disease and hypertension, a short course of oral decongestants like sudafed might help also. You can't use afrin more than 5 days.
