I've been talking on this forum recently about low BG and concerns.
In my case it is a Freestyle Libre 2 giving the readings and the sensor was reading a bit low.
I was getting warnings of 3.5 (or lower) and dropping.
I don't get hypo symptoms, though.
Real value was probably around 4.0/72.
My feeling was that although T2s "don't get hypos" and the CGM is really aimed at T1s who may not get the same "stop making insulin start making glucose" effect that T2s get, I would have a little something "just in case".
So I understand the anxiety.
However a value of 4.0/72 is low normal.
Some people have a fasting BG of 3.5/63 (including a diabetes specialist I know).
So I don't think the numbers you are seeing in themselves are low.
As you have noted, the real problem is the false hypos.
I would suggest trying to treat your diet as if you had Reactive Hypoglycemia because you are in effect forcing yourself onto the roller coaster.
If you are having 5-10 grams of carbs at regular intervals then you must be taking in a lot of carbs over the whole day. You might look at reducing this significantly.
If one strawberry spikes you, then that should perhaps be taken as a baseline and try half a strawberry, or a quarter. If you take small amounts of fruit then there isn't enough carbohydrates to have a major long term effect.
If you slam in a banana and a bunch of grapes you are going to spike big time.
Grapes are rocket fuel so probably wisest to steer clear.
Alternatively you could try the famous jelly baby.
Try one jelly baby.
If that is too much, try a half.
Just bite the head off.
Also, give it a little time to work.
It might take a few minutes to kick in, and it is easy to take more because you think that it isn't working.
Tough to work through this given your other complications, but I think you might be better setting your "panic button" BG level a bit lower in the hope that the false hypos will moderate.
