OK, this is the key - if you are on gliclizide then you MUST be prescribed test strips. Hypos on metformin alone are very rare, but gliclizide can definitely cause them. Your GP should know this, and if he doesn't then he is being negligent in his duty. Do you drive? It is a legal requirement that you test your blood sugar before driving to ensure you are safe to do so (and during the journey, if it is a long one). You also need to be able to test if you feel symptoms of a low blood sugar. Your GP is wrong if he is disputing this and I would enlighten him - if he still insists you don't need them then seek a second opinion.
I'm still not convinced that you are Type2 and it may be the addition of gliclizide (along with your very strict and restricted diet) that is keeping your levels under control. Gliclizide prompts your pancreas to produce more insulin, hence the danger of hypos. Metformin simply reduces the impact carbs in your diet, and I believe normally has no more than a 10% improvement in levels. The path of a typical Type1.5/LADA is the one you are following: metformin alone, small improvement; metformin and gliclizide, large initial improvement; eventually (often within 12 months) the gliclizide no longer works and you need insulin. Many of our members have followed a similar path. Since your GP appears ignorant of the fact you need to test on gliclizide I would be doubtful of his knowledge regarding the more unusual ways that diabetes can manifest itself.
Regarding the test meter you have bought - it would be cheaper for you to get the
SD Codefree Meter as you would then save around £11 per box of
test strips for it, so you would pay for the meter with your first box. But definitely go back to the GP and don't leave without getting a valid reason why he won't prescribe strips (there isn't one!)

Regarding lancets, it is a running joke amongst diabetics that we change our lancets once in a blue moon, or on St Swithin's Day, whichever comes sooner!
