However, my doctor pulled me off metformin because it sometimes messes with ALT levels, making it difficult to get an accurate picture
of how liver enzymes respond to tx. I ate so little during tx, and a lot
of it was ice cream. Nevertheless, for some reason - despite all the sugar in ice cream - my A1c was better during tx than it ever was before or after. Now, a year since finishing, I'm back on metformin and my ALT and ASt are wonderfully low (21 and 26 respectively).
