Erin's getting really good at this. She's able to tell a low's coming on in the low 80's now. When she first was diagnosed she had several 40's. She never gets that low anymore. Her highs are a bit harder, she feels hungry, so it feels like the low to her. She says her low symptoms are a bit shakey when it's not super low. She knows she super low if her tummy is "itchy" or "scratchy"- usually that's in her 70's or high 60's.
