There haven't been a lot of studies, but I know of a couple of folks who feel like you do. That they have lost function and don't remember as well. I do remember one guy who posted on a number of boards a lot was proud of the fact that he ran very low all the time. His spelling got worse and worse and his coherence decreased significantly too and eventually he stopped posting.
I suspect that damage is as possible from low blood sugar as from high blood sugar.
The only way to know if it's ok for you, is to check your blood sugar. If your blood sugars are normal, then it's ok. For many people, stopping a med (bp med, insulin, whatever) is kind of like taking the patch off a leaking pipe. The pipe will leak again without the patch, just as your blood sugar will (probably) go up without the insulin.
Hypoglycemic unawareness occurs when you spend too much time too low. There are other factors in that some folks are more susceptible to getting it, but it happens most often when your body gets used to the lows and starts ignoring them.
If you don't mind my asking, what have your a1cs been? Do/did you go low often? In some people, running high (consistently) for a month or so can help to bring the signals back. But most folks don't want to do this because they are simply unwilling to run high for a while (although certainly not long enough to cause any damage).
Interestingly enough, hypounawareness is one of only 2 qualifiers for a pancreas transplant (kidney failure/transplant is the other). With a new pancreas you wouldn't go low and would get used to steady glucose levels. But you will be trading one set of problems for another potential set of problems (anti-rejection drug side effects).
Yup, the winter is getting to us all. I know about the slow recovery. My hubby brought the recumbent bike up from the basement ('cause I was afraid I wouldn't make it back up after pedalling). But things will get better.
Hey there Flute. What, you don't like the "rah! rah!" type comments about "good for you seeing your doc"? And the ones that simply say "see a dietitian"? At least we're not seeing so much spam about "hit this link and cure....".
The confusion is part of why I'm not posting so much. The good news is that boards go through phases and then typically go back to "normal".
How are you doing lately? I am doing very well. The occasional low as I now have a bit of reactive hypoglycemia. But otherwise I have some energy and am doing well.
I think it was a bit of a bogus experiment. They both, allegedly, did zero of their "bad" substance. Here's the problem. Even a LCHF diet has some carb - so you don't get constipated and will get all your nutrients. And a low fat diet (like Pritikin) allows healthy fats including certain oils and things like avocado. So neither twin was a realistic description of what "real" people do or any of the so-called "fad" diets.
