I've been a type one diabetic all my life, and I take care of my diabetes as best as i can. Most of the time i have good blood sugars, but some times they seem to rise up for no apparent reason. The last straw was last night when i checked my blood sugar before bed and it was 150, which is good for me. I then proceeded to do my dose of Lantus and went to bed. When i woke up today my blood sugar was 200. If anyone has any answers or ideas on why blood sugars spike for no apparent reason, it would be much appreciated.
