Oh Emily.....I can totally relate to this. Especially the waking up in the morning thing. Here's hoping your day got better. I'm with you in spirit today.
Y'all are so wonderful!!!!! Thank you all so much for your comments. The suggestion to re-test is a VERY good one... Which I rarely follow (especially in the middle of the night).
Last week I woke up at 4:00 to my alarm, which I had set because I've been going low almost every morning at about that time. I was 52 and felt pretty sick. I boosted, went to 69, boosted again. When I went to bed I was 158. At 7:00 my meter said HI. I said HI back and had and treated it cautiously. A few hours later I was 39. It happens sometimes, and it sucks, but you just have to deal with it and look at the bright side. :)
