I have been sick three times tonight, after dinner and have just done my bs and it is 2.6. I have been told if it is below 6/7 before bedtime to have another snack. I am new to this. I have just had some fresh orange and will take another reading in 15 minutes or so but what if it remains low???????. I am not regulated yet and I think the hlf glizlizide I am take at night with my 1000 Metformen is taking me too low.
