I test 12 times per day. I have found that the more times I test, the more stable my control will be. I use very tight control and frequent testing is an important part of my routine. Tight control has helped me to live 65 years with my diabetes and I am very healthy. I know some diabetics who can test only a few times each day and get alog fine, but I have too many fluctuations in my blood sugar, and 12 times per day works well for me.
