I get what you are both saying. That makes sense, but I'm thinking that, in theory anyway, the readings will hopefully ease down more each day with the same dose, as his own pancreas picks up the slack, and by the end of the week if still falling on a declining slope, then keeping the same dose would take it further downward the following week. Upping the dose, then may drive it too fast downward, and rebound. As long as he is eating the same food and amounts, and other factors remain constant, as well as the dose, I would think that his levels would not fluctuate much. And his ears have red splotches-bruises, (whatever they are), all up and down both edges of both ears.
Yes, it was hard to get the swings under control at first, with the scale. But when we started to, it was holding relatively steady at 1.5, then 2, then 2.5, even if not for entire weeks. I guess you have to decide between waiting longer for results, or risking bounces.
