@Scandichic, I, and several others on here get the cheapest BG meter we can - the Codefree one. You can order it online,
this evening on Amazon or eBay. Cost you about 20 quid to be up and running with 50 test strips.
I cannot recommend self monitoring enough! It helps you see what eating certain foods is doing to your body. And gives you daily reasons to make better food choices.
The blurred vision you are getting is a sign that high blood glucose is significantly affecting you - and it will be affecting you in other, invisible ways too.
Have you read up on what healthy blood glucose levels are?
