Lows

We're doing something wrong, not sure how to fix it. K's been having a series of low morning blood glucose readings, and they really wipe her out. We try to never let her BG get below 90, but the past week we've seen 55, 41, 38, and now 48 this morning. The rest of the day usually consists of wild swings into the frighteningly high range, sometimes pinning the meter at its highest possible reading of 600. This lack of BG control is very disheartening.
