Thanks Dew -- I don't think I'm going to push the a1c any lower than 5.6%, but you never know. Forgot to mention, though, that tight control comes with one adverse consequence, high incident of severe low blood sugars. However, one can offset that by testing frequently and having fast-sugar treats around to counter these episodes. I've had a few scarey lows for sure, but never had to go to emergency room.
I believe that the 6-6.5% range for a1c's is more realistic and better target for the general diabetic population.
Since I am more of a control person, I like to push the envelop a bit. Now if I can only qualify for the Boston Marathon this fall, I'll be a happy camper! Missed qualifying by 23 seconds this past March. ;)
