Sinus Medication Solution

It is my birthday and I have a sinus infection…..coughing at night, clogged ears, itchy throat. I do not believe in antibiotics so don’t tell me to go to the Doctor. I have taking otc meds for symptom relief but it only lasts for four hours and is not helping. We are going out tonight to celebratemy birthday and I really don’t want to feel horrible. Please help
