I have Type 2 diabetes, so I am talking from a (reasonably) well-controlled person with Type 2's perspective.
I have to say, not all of us are so absolutely sure that testing our blood glucose levels, especially in the first month or two after diagnosis, is absolutely essential. I test myself a couple of times a week. Just to check there's nothing major going on. If there is - and there never has been - I'm be off to the docs. Initially, as I think most type-2s who don't have really high initial BG test results, I watched what I ate closely and exercised a lot more. Which was good as I take enough pills already ;-)
But, although it improved, I went onto metformin within a couple of months. I can't remember how long, it was probably a month at most. I then tried adding a low dose of metformin, which didn't make enough of a difference so I'm now taking 850mg 3 times a day. I started testing my blood after I'd been using the metformin for a short while - again, I can't remember exactly how long.
My BG has stabalised near the top of the 'good' range. So I test a couple of times a week.
If I'd been told to test my blood 2 times a week when I was first diagnosed I'd have got even more obsessed than I was! It was not health, and I believe would have ended up with me probably eating chocolate, not looking after myself and not seeing my gp and diabetes nurse again. I certainly felt like doing that anyway! I tried my best to control my GB levels, then felt a total failure when I couldn't. The levels were coming down, but by nowhere near enough. If I had been testing my blood at that point, I may well have got so stressed who knows what would have happened :-(
Is stress supposed to raise BG levels? I don't know.
I understand that it's totally different for people with type 1, or who's BG levels were worse on diagnosis than mine.
