I split my Levemir, 16 units in morning at 16 at night, sometimes I can wake up at 3 and sometimes at 18... I can't work it out and I've been diabetic 11 years. There are people out there who worry if their reading is over 6 - I feel low at anything under 6... it is definitely each to their own when it comes to readings and doses! I would love to have better control but I just can't do it and I don't know why... I test about 6 times a day and it's always SO random I can't work it out. I can eat the exact same thing day in day out and have readings differing from 4 to in the 20s. It's crazy!
