A lot of us do - although most doctors say that we don't need to. So be prepared for your doctor to disapprove.
Diabetics on insulin get the meters on prescription.
The rest of us... it would be very rare.
When you choose a meter, bear in mind the ongoing cost.
The average meter uses little tubs of 50 test strips, one test per strip.
I tend to test 5 times a day (but there are no hard and fast rules, we each decide how often to test).
So a tub of strips lasts me 10 days.
As a result, I went for the cheapest meter I could find (the Codefree, £13 the meter, £6.50 for £50 strips).
Other meters could cost you £25+ for 50 strips!
