I test my blood glucose about 5 - 7 times daily. Each one of those tests requires a lancet and a test strip. I take insulin 5 times a day ( 3 Novolog, 2 Levemir ). Each one of those shots requires a needle. That's 35-49 test strips and 35 needles in one week. Or looking at it another way; I punch over 70 holes in my body each week.
