Crazy blood sugars

Crazy blood sugars again today. We keep getting lows and sometimes they are hard to get up. They start out being between the 50's and the 70's and sometimes don't go up until the third try. It makes me nervous because among our many directions from the Endocrinologist is to call immediately if you can not raise a low blood sugar after 3 tries. Today when I checked her blood sugar for the third time the meter read 557. I didn't even know the meter went that high. I almost freaked!!!! Then I remembered that she probably had something sweet on her hands since I had given her sugar tablets to bring up her blood sugar and I might not have washed them good enough. Thank god when I read it again it was 136. Yahoo!
