Thanks to someone, I do not remember who, wrote about 'Sterimar' and how good it was for people using O2. I was unsure if I could buy it here in France, but, no problem, and about the same price. My nose is no longer hurting and in a very short time.
This site covers so much and we can learn about little things and big ones as we browse.
Thank you BLF! Lolly.
