Thanks Muffin43 that helps a lot, plus thanks fradley1:-
I do have a slight cough, but it isn't anything that bothers me much, as I get a lot of chest infections anyway which I believe is due to my tastebuds changing. I used to eat a lot of veg etc, but now can't stand the stuff especially colli & brocoli. My buds have gone as they were when I was a child when I only eat tinned veg such as peas & beans, so think my vitamins are out of sync. I intend asking my gp next week when I see her about it.
Cheers,
John
