Hello Fifer welcome to the forum.
When I was diagnosed in October 2009, the DSN gave me a meter and strips and provided me with some really good guidelines on how to use the meter and what blood glucose ranges to aim for :
Before meals : 4 - 7 mmol/L
2hrs After meals : 7 - 9 mmol/L
Avoid > 10 mmol/L (hyper)
Avoid < 4 mmol/L (hypo)
I was also advised to test once a day at different times (before breakfast, 2hrs after breakfast, before midday meal, 2hrs after, before evening meal, 2hrs after and finally before bed). This works well if control is gained quickly, but if you have problems, then testing before and after a meal on a daily basis would be better. The advice already given tells you how to do this.
The simple advice given to me allowed me to get good control pretty quickly, though. So much so that I was able to stop the medication after three months.
In addition, I was also able to attend a course run by the NHS called Diabetes X-Pert (there are others available to, DESMOND being one). This gave me all the information I needed to understand what Diabetes was and how I could best control it through diet and exercise changes. It also covers all the medications available.
When you next see your healthcare bod, ask whether there are any courses in your area.
In the meantime, just ask questions here. Eventually, you will work out a regime which works for you and you can start looking forward to controlling your Diabetes rather than it controlling you.
Good luck,
Andy 🙂
