After another visit to the doc - a GP registrar whom I'd never seen before - He prescribed a different type of inhaler called a Breezhaler; a capsule that's inserted into a little gadget, pierced, and then inhaled once, just once a day. I can't believe what a difference it's made!! Why did it take 3 docs' visits to be given this?!
I now breathe normally & hardly even cough! A new lease of life!
When I got it from the pharmacy, I had to give them a phone number, as they said that after 2 weeks, they would call me to find out if it was working, so maybe this medication is on some kind of trial? It's indicated for COPD, although I have never been diagnosed with this. Anyway, I'm very grateful for it!
