What do you know of 'glycemic instability'?

I feel certain that this is whats going on here. Have dropped from Lantus = 35 to Lantus = 31, but will have to drop farther. People are suggesting, maybe, 8 or 10 units of decrease might be required in order to recover system stability. I think I have been living most of my life in a state of glycemic instability. Dropping the Lantus seems to have fundamentally changed the system. Extreme highs have almost disappeared, as well as most of the lows. I didn't expect the highs to decrease from dropping my Lantus dose. Its a bit counter-intuitive.
