Is it truly possible to attain an hbA1C of 5.5% for Type 1 diabetes?  It's possible, but when I hear about the T1 people who appear to deftly get into the normal range, I ask them the question, "Do you ever get hypoglycemia?"  The answer is always yes, and every day.  I just don't think the technology we have is ready to handle this, and if I had to weigh being around 7.0% A1C or hypoglycemia and being brittle every day, I'd surely take the 7!
