I am pretty sure that my mother has hypoglycemia but, try telling her that! hhaha..
She'll be standing there with her hand completly shaking taking a bite of something and has the nervousnessness to boot also mixed with vision blocks when she eats something too sweet at the wrong time.
I have it and my grandma I think had hypoglycemia too but she also had something where her white blood cells started taking over her red blood cells and she passed away at 54. this makes me wonder if hypoglycemics have a slightly higher white blood cell count. I too was found to have a high count right after my baby was born and they told me to inform my doc but I forgot to tell him that...
I do think insulin problem are hereditary.
You do sound hypoglycemic.
