I have had it too, it lasted for months and I became very ill, I am only just getting over it now - as in, I only cough for maybe ten minutes each morning and perhaps the same mid-evening. I really wasn't resting enough. It was only when DBH went away for three weeks that I started to recover properly. I had been coughing for so long that I did need antibiotics - because I had made my throat bleed and something the name of which I have forgotten, deeper down, and a chest infection. I ended up on them for a month in the end until they found one that worked, and I survived and only got enough rest by taking sleeping tablets and lots of day nursed, which by stopping the symptoms allowed things to heal up. The Drs said I had a vicious circle going on.
I do feel for you, it felt as if I was going to be coughing for ever, I felt like a smoker - except I have never smoked. It used to take over an hour before I dared to get up in the morning, because movement set it off.
If I hear anyone cough between now and Christmas, I shall just run. It was a party this time last year that set it all off - a friend with the 100 day cough that didn't want to miss out on the fun. She passed it on to pretty much everyone there, having dosed herself up first although feeling really rough. The same party is on tomorrow night and the hostess has sent out the invitations with 'No kissing allowed at this party, face masks acceptable attire' at the bottom!

All the symptoms on the NHS site fit what I've been experiencing. There doesn't seem to be much you can do about it, although if I'd known I would have been even more careful about passing it on! 3 to 4 months seems to be the duration so I should be ok by the end of January.
