I have been reading the comments on this site for at least six months. First time I am posting. I am from the USA (CT), but have found British sites/sources to be more informative than American. Maybe the NHS versus the privatised US. I am in end stage COPD and now on a daily regimen of Zitromiocin, based on a study written up in the New England Journal of Medicine. My doctors and I have tried all else. Since I am an Anglophile, I can understand many of the references in your posts. I have not been able to find a comments site like this in US sites.
Thanks for the info many of you have posted. Is there anyone else like me who is a Yank?
