Ok.... update time.
8 weeks between last endo appt and endo appt today:
last a1c 7.9
weight: lost 11lbs
Doc not impressed with the a1c, which pissed me off, because there were a lot of night time lows. As for the unexplained insulin resistance taking place in the past week or so, the doc gave me new insulin and asked me to see if this makes a difference. If not, blood work to rule out other possible causes.
