Sugar meter

Hello good friends, I would like Seber because diabetics without Isulina do not give us the sugar meter.
As I will know, what affects me or what feels better or not.
The truth is disappointed.
Thank you.

For an economic and simplicity issue.
Insulin is the only drug that produces hypoglycemia (it is not true that it is the only drug, but to simplify, it is said so) and for that reason, in many places, they restrict reactive strips.
