The readings you are postings very worrisome!
Hellow again Bulkbiker after so long a time.
I see that you have "added a word" to Lamont's statement = "unmedicated".
When I was on just tablets I used to wake up bathed in sweat and when I tested it was about 2.5 At other times it would be about 3 or 3.5 Once I had violent "rigors" whilst driving a car and I didn't have my test kit with me.
Now if it heads below 4 I start to take corrective action. Fortunately, I always wake up before things get too serious.
Have a nice day.
If you are continually getting these readings, which along with the high readings in your other post, there is clearly something going on, which is atypical T2!
It maybe the glicizide, or the insulin wether natural or injected that is driving down the glucose levels!
But what is driving up glucose levels to the high levels?
I don't know your dietary regime is! But because of the high levels, there is something that is doing this!
I would suggest a second diagnostic with a different doctor or a referral to a specialist.
Glicizide and insulin is not a usual treatment for T2, unless you are insulin dependent, but even that is unusual!
I was misdiagnosed with T2, my readings were never uniform except for fasting, which because I didn't have dawn phenomenon, it was noticeable in my food diary and along with my hba1c levels, that I couldn't be diabetic to my specialist. But I still had high glucose levels after carbs, and then had lows, I was not on any meds except metformin, which was stopped immediately.
Maybe, The reason why you are having brain issues, and I've been there before my true diagnosis, is that brain function will definitely develop problems when blood glucose levels are on a rollercoaster ride up and down, due to hyperinsulinimia or hyperglycaemia or both, with insulin resistance and your hormonal response is not enough or too much!
Do try and get sorted. Something is not right!
My best wishes, take care!
