So, out of curiosity, what do other T2s on oral meds do?
By the way, just before, 2 hours after lunch, my reading said 6.4, the lowest so far.
Fair question. I'm not T2, but have a reasonable start on this; my late brother was T2.
Ideally test immediately before the first mouthful of a meal and test as close to 2 hrs later. You are looking to finish at 8-8.5 mmol/L or under 3 mmol/L increase. But this is your end game; so if you start the meal higher, then the target is to NOT have more than 3 mmol/L increase. This will tell you that your meals was managed acceptably by your body. Otherwise you need to mix and match with: reduced portion sizes; avoid the high carb hitters, such as potatoes, pasta and rice (and more obviously desserts with full on sugar); make substitutions such as loads more green veg for potatoes, grated cauliflower instead of rice and pasta made from Edale beans rather than traditional wheat. The 2 hour wait is important for consistency and this is also a sort of loosely accepted standard for confirming your body is managing that meal. Those mix and match suggestions are just that: mix and match and one doesn't have to do all of them.
Your HbA1c at 75 is clearly in the D zone, but it's not so alarming; we see people posting from a start point in 3 figures. And you don't need to respond excessively dramatically, it's far better to try and find choices you can enjoy and routinely select as part of a new but naturally acceptable lifestyle. Your choices need to be sustainable by YOU or the effort will probably fall by the wayside.
If your start point for a pre meal test is higher than you really want then some initial "tough love" with carb control would be needed. But from what you've said your 6.2 and weight loss so far is great already.
All this testing might seem excessive and a potential burden. So the basic structured testing could readily be adjusted. Perhaps (just one suggestion) test for all meals once in the week to have some bench marks for comparison. Then systematically just sort out one meal at a time. Many people start with their breakfasts, partly because it's the 1st meal of the day, partly because most people have their highest degree of insulin resistance at the start of their day and partly because most people choose to have a very repeatable breakfast daily. Get breakfast sorted, reduce or stop testing for breakfasts and repeat for lunches. Then dinners. There are endless permutations to fit into your normal routines.
If having snacks is part of that lifestyle and too challenging to just stop snacking, then try to find snacks which are extremely low in carbs; I don't need to do that since I am I sulun dependent but if I'm being lazy and want to duck a small insulin dose for a snack I'll make something like a breadless sandwich from a couple of cheese slices and a ham filling. In practice there are many options, just needs some creativity with carbless foods that I like.
As you increasingly become carb aware, you will quickly learn which individual food items work for you in isolation and in combination with other foods. Items on their own might be ideal but combined with something else could produce a very different outcome.
