I certainly am!
I have a very pro-active GP who immediately put me on Metformin as soon as my pre-d was identified in a routine checkup.
My fasting then was around 6.0 (with no real symptoms), today it is middle 4s.
Some weeks ago, I changed form low dose Met (2 x 250mg/day) to Glucobay, as my BG, while generally pretty low, did hit minor hypos, followed by a short spike. (Glucobay has fixed that, very stable now, standard deviation of the last 100 readings (fasting, pre and post meal is 0.3)
My latest HbA1c last month was 4.7, so I'm well on the way to halting progression, if not actually turning the clock back a bit.
My GP feels quite strongly about early intervention, rather than trying just exercise/weightloss/diet first (though I have lost well over 100 pounds and exercise more too) as he feels that there may well be something in the reports of partial reversal of beta cell decline, if managed early and in an aggressive fashion.
I've read reports of prompt, intensive insulin therapy to pre-diabetics for a short period leading to complete remission.
It might be worth seeing if another doc in the practice is a diabetes early-interventionist...
Mark.
