When discussing asthma it can be too easy to jump in with an uninformed opinion, especially without knowing the severity of your condition. So, with that acknowledged...
I was a sufferer for 30-odd years, with a few hospital admissions and periods on the nebulisers, but mostly kept controlled with daily Becotide and Ventolin as needed, which was a few times a day. I was certainly not chronic, but it affected my life for a long time.
Then I came across the Buteyko Method. Within 2 days of reading about this and starting to practice it, I put my inhalers away and have not used them since, which is now 11 years. Naturally this has turned me into a huge advocate for the method, but I know it is not a miracle cure for all sufferers and you should not do this sort of thing without support from your GP.
There is loads of free information about this on the internet, and probably lots of paid information too. I didn't need the paid information, and I suspect it adds little to nothing compared to basic, simple, free method. I'm happy to receive private messages about this too as it's somewhat off topic. I urge you to look into this if it's not something you've explored before.
I appreciate this might sound spammy, but I have nothing to gain through this post except...well, after lurking here for a week or two I've initially joined just so I could post this message to you, So maybe now I'll de-lurk and post a proper Hello post and get chatting :-)
All the best,
