My parents both have it and been quite rough. Not sure if I gave it them or vica-versa. For me mainly started as a bit of an silly dry cough and hoarse throat early December. Second week of December, silly dry cough became a productive cough , constant hacking and coughing with associated crud on chest and snotty nose. I think I've just completed the fourth week of it. Weird thing is, I haven't felt all that ill with it, but god that cough has been driving me up the wall. I don't like to speak too soon but I may finally be on the mend with it. I've thought that a few times and been wrong, but the time it has been taking to shift it's unbelieveable. I don't smoke, but I do vape which I've kept to a minimum. Got a trip booked for new year in the van, tentative depending on how things progress over next few days, but I will probably go provided the night time coughing carries on decreasing... Don't want to be keeping the site awake. Finger s crossed.
