Thanks to everyone who replied to my posting on the above. It would appear not all medication suits everyone as I hinted at as I have come across this a long time ago. Seems that Trimbow has to be given a while to take effect. So I have decided I will give it 2 or 3 weeks & if still not feeling as well as I was on Trelegy then is will ask to be changed back to Trelegy.
Thanks again
