You can also watch some great short videos on you tube. Real people who have been able to really control their blood sugars. They tell you how they have done it. Also great videos from health care professionals. Jason Fung is one to watch. Very informative. Just input his name + diabetes in Google and click on video.
I would just like to ask if I may, whether or not you know your hba1c? Mine was 62 at diagnosis (anything over 47 is classed as diabetic). I changed my way of eating to low carb straight away after finding out on the internet just how many diabetics were having great success by eating this way. On my next test after 2 months it was down to 47 (42 to 47 is classed as pre diabetic). Then in another 3 months it was down to 41 (anything under 42 classed as normal).
I've been lower at 39 on subsequent blood tests. I've avoided medication, so far. All by changing the way I eat. So what I'm trying to say is that diet can be a better medicine. Metformin doesn't have much impact.
There is a lot to take in. I'm 18 months in from my diagnosis and still learn something every day.
