you can buy all the supplies to test your blood sugar at walmart or a pharmacy.

we bought a kit for one of my daughters this spring. she was having all the symptoms of low blood sugar. she is fine. we found out her apartment was old and unlevel. she was having vertigo and felt dizzy. like with low blood sugar. plus the place we suspect had mold. thankfully she has moved.

the supplies aren't cheap, but was less expensive than a dr's visit for a test. if the tests had come back with porblems, then she would have gone to a dr.

the tester came with a dvd and a website for support. i think most of them do.
