Hi Zelda, Just a reminder...when you get a significant drop in numbers like last night - he went from 288 to 109 in a couple of hours it would be advisable to get another test in an hour...yes, I know, miserable to get up again in the middle of the night.
But with Walter's history of plunging then bouncing to the moon, it's the only thing you can do to keep him away from those lower numbers...if he was headed down much further than 109, it would call for MC/HC food to steer him away from those sharkies (lower green numbers)...
Hope this helps for next time.
