Thank you for the information.
Given its ineffectiveness, I would be inclined to suggest discontinuing Ulone, and I don't recommend Advil Cold & Sinus either as it can increase anxiety and symptoms of anxiety such as palpitations, tremors and insomnia.
Coughing is most often caused by sinus drainage into the throat, like a leaky faucet.
For this purpose, I suggest nasal hygiene with a saline solution (Hydrasense, Sinus Rinse and others), which can be done as often as necessary during the day, and at least 30 minutes before bedtime. By 'cleaning' the nasal secretions, we can reduce the feeling of pressure in the sinuses and prevent them from flowing backwards into the throat, which can be irritating.
I encourage you to drink plenty of fluids, cold or hot, as you prefer.
If the symptoms persist for more than 7 days without improvement, you should consult a doctor.
I hope I've been helpful and I'm available if you have any other questions!
