My wife was feeling really bad with coughs and sniffles. Said she had the flu or a virus.
After a couple of days I remembered something - this is August in Melbourne, and we'd had a couple of north wind days.
I got her to take some anti-histamine pills (non-drowsy ones during day, Polaramine at night), and my wife was cured.
I knew to do this because the same thing had happened to me in August many years ago, when after a week of suffering what I thought was a terrible virus and taking Codrals and Sudofeds, I crawled in to see the Doctor. He prescribed some Rhinocort, I sprayed it up my nose, and was cured half an hour later.
Regards,
Renato
