There are meters available mail order, which seem to be far cheaper to use than many - I am sure that there will be someone able to give you the website to use, and there are even codes to use for discounts of bulk purchase of strips - the lancets are available cheaply from pharmacies so it is hardly worth paying postage on them once you have the basic kit.
If you can do without the tablets, I can only advise that you do so - I got all the side effects with Atorvastatin and Metformin and had the most miserable few weeks until I just gave up on them. Life was not worth living.
My memory has improved a bit recently, but I am sure that any test done a few months ago would have put me in danger of a diagnosis of dementia. As a singer and musician that has been a bit of a disaster for me, but thanks to the internet I have been able to look for the words and listen to the tunes, and as a bonus I have been able to read some really good books.
Although I have been encouraged to take statins now that they have been removed from the repeat prescriptions (I need Thyroxine for life) my getting normal readings when tested for Hba1c and blood glucose seems to have made me very uninteresting to my doctors.
