I had a virus at the beginning of April, got better from that, but right at the end of it, I started to cough. It wasn't horrendous, but it felt like a constant little tickle in my throat. Going in and out of rooms or areas with different temperatures used to set it off. also kept feeling that I had some phlegm constantly stuck in my throat. Such a nuisance. Decided to take some ibuprofen to calm it all down, which seemed to work. Didn't take any cough mixture as I did this when I had a similar cough in September 2014 - that cough took three months to go and I took so much cough linctus I ended up having to take a day off work because it had given me a bad case of the number twos. The cough seems to have sort of gone now, so I'm crossing fingers. Commiserations to you and your wife, fishing81, hope you both get better soon.
