Blood sugar / glucose monitor?

I firmly believe that A1c tests are biased towards the shorter term levels.

My doctor tells me what the glucose reading was at the time of the test as well as the average.
In the nearly 20 years I've been diagnosed, I've noticed that a good week before the test tends to offset a bad 2 months before that and vice-versa.

What I have is a relatively newly "discovered" "late onset" type 1.
The normal type 2 medications have very little effect on me and it took years and multiple doctors to figure that out.
I'm actually happy to be on insulin rather than marginally effective, highly refined pharmaceuticals with questionable long term side effects.
Fortunately my doctor and her associate, my previous doctor actually listen to me.

I quit taking metformin in January after proving to myself that it wasn't doing anything.
I had to creatively prove it to the doctor by not telling her I wasn't taking it until after the A1c.
...but it worked.

When I started taking it, I had every single one of the 16 plus or minus side effects and it took over a month for them to clear.

I am now on 70/30 (mid-acting/short acting) insulin before meals on a semi-sliding scale of 100 units total per day.

My A1c tends to bounce between 6.8 and 7.2 every other test, so I am reasonably happy with that.

The log posted earlier is typical. for me as well.

If I'm high, say over 250 for very long I get super lethargic and don't want to get off the couch. If I went to the hospital every time I was over 250, I couldn't afford to live. I just give myself 10 or so units and check again in an hour.

If I'm low, say under 68-ish, I do get shaky and cold sweats and can have trouble making complex decisions. My rule is- If I have to ask myself "can I finish what I'm doing, or do I need to eat now", the answer is always "eat now".
