Yup, I'm sure this happens to a lot of people (though not me- YET

)... but, anyway, I think having a disease that requires so much discipline and self-management, it's easy to want to ignore (maybe that's not the right word) it at times.... You aren't just a diabetic, you are a person who has a life and Diabetes shouldn't be what your life is built around.
I'm glad that you recognize this issue yourself... And, for your health's sake, I would hope that you plan to be a little conscientious about testing and taking care of yourself. If it's a struggle to regain control, make small goals and take small steps

- you'll get there

.
Good luck.
