Well, the last visit to the doctor wasn't good. I did get a flu shot, which didn't kill me, and they took some more blood. Tests turned out not so good - weight was back up to 416 and A1c was up to 8.3, so the NPH insulin dose went up to 20 at bedtime and in the morning.
This seems to have helped, if not immediately; perversely, the daily average blood sugars rose into the 200-250 range until this week, when they started falling back under 200 and are now around 150, which is better but still not good. It makes me wonder if the loratidine I was taking for allergies is somehow screwing with the glucose...certainly I've been seeing lower daily readings since knocking it off, but correlation is not causation.
Right leg continues to heal and the outbreak in the left leg is also going down. Need to hit the pool, especially since I now have "support stockings" to help cover the ulcers.
Ironically, the excellent scale digex loaned me is sitting uselessly in front of the walk-in closet. Its battery is dead and the adapter has not yet made an appearance.
