Meters vary and people vary, the rate your blood sugar goes down can also affect whether or not you have hypo symptoms. A fast drop is more likely to cause a hypo than a slow drop. Age is also a factor, a young person with reactive hypoglycaemia is less likely to have hypo symptoms than someone who is middle age.
I've had reactive hypoglycaemia since my early 20's but didn't have serious problems with hypos until I was 30. Ironically, the treatment offered was metformin which tempers the highs and in doing so prevents the reaction that causes the hypos. With reactive hypoglycaemia, if you can keep your blood sugar levels fairly even by eating small amounts at regular intervals then you don't get the hypos. The alternative is just dealing with the hypos, but that's like chasing a dragon -- sometime you can just about keep up, sometimes you get burned.
It took a long time before my GP believed me, I ended up having a hypo at the surgery before they referred me for a GTT. Log your meter readings and symptoms, that is the only proof you have that you are having hypos. Use that when you ask for a prolonged Glucose Tolerance Test.
