Thanks for the advice but I don't think milk is an issue for me as I haven't liked it since an unfortunate experience with school milk when I was 4yrs old! Barely have any milk, a few drops in my tea that sort of thing.

To be fair I don't think I generally have a chest / breathing issue. This is probably my first proper chest infection since I gave up smoking 14 years ago. I think it's just that I'm so run down, which is what the docs seem to think too. Hence wanting to improve my general immunity. Doesn't seem to be working though as I've been prescribed yet another course of antibiotics. Not started them yet though as I'm a little concerned about what repeated courses of antibiotics will be doing to me.

6 weeks off work so far. My sick pay has just run out and no sign of me being fit to work yet :boohoo:
