A T2 diabetic not on medication is unlikely to be offered a BG meter nowadays, but I think you NEED one. Contact Abbot Diabetes care . They can supply a Freestyle meter with test strips. The booklet with the meter will explain how to use it. NICE says you have the right to BG testing, when newly diagnosed. You need to find out what effects foods have on your BG. You may have to fight for test strips. You should also be offered a DESMOND course. (I never have been in 5 years :? .)
With my Freestyle Mini meter, I test on the inside of my forearm. If I press the top of the "stabber" onto my arm, I cannot feel the stab. (I set it at 2)
With the numbers you tell us, 7.1 and 7.6, it shouldn't be too difficult to get down to around 5, by reducing your carbs. If you follow the "healthy plate" 1/3 full of carb foods, you won't.
Abbott won't charge much for a meter, they make their money on the strips. Their website was down, but it might be back. Anyway they are in maidenhead Berks, if you have to resort to a phone book.
