First off, congrats on your hubby's A1c. 6.8 is still a tad high but much better than than the 11.8.
When was the last time your hubby calibrated his meter? Also double check the test strips for they too have expiration dates.
my blood sugar drops to about 59 im on meds should it be dropping that low
If my blood sugar goes down that low I begin to sweat and shake. I'm not sure what the low number is when one goes into a coma, but that is tha danger. When I get lower than 100 I drink a small glass of chocolate milk to get it up quickly. Many people use Glucose tablets that they carry with them. The problem is that if you spike it up with pure sugar it overcorrects in a short time. You need to add some protein, such as milk.
There are definate severe problems that happen with low blood sugar. It's possibe that your husband needs to have his meds adjusted.
Good luck,
Janni
