I am so sorry about what you are experiencing. This is the nightmare of all insulin dependent diabetics, going low in the middle of the night and not being able to wake up. I am not a doctor, so my advice comes from 40 years of experience with Type I Diabetes. There will always be some swings with daibetes. There are so many variables; food, exercise, hormones,stress, illness, etc. Many of these can't be controlled.
