cough and nasal congestion
"I’ve been coughing for days (unable to sleep because of the cough), can’t breathe through my nose and have a congestion headache. Took 2 pills in the morning and it took a while to kick in but several hours later I realized I could actually take a full breath through my nose, headache improved, still coughing but not quite as bad. I didn’t have any issues with feeling jittery or wide awake."
