Dear,

If i go to bed with BG of 6 mmol and i'm using lantus before breakfast. Am i going to experience hypoglycemia during sleep? I'm anxious about it and i usually keep my BG at least 9 mmol before going to bed in order to prevent hypoglycemia.
 
If you need to be at 9 before bed to avoid hypoglycemia during the night, the Lantus dosage could be too high. Basal insulin with a shorter action profile may be more suitable. Levemir doesn't last as long as Lantus. I also take Lantus in the morning and I have to be careful I don't go low the next night. For most people it is not a problem because of the dawn phenomenon early morning blood glucose rise. I would reduce Lantus first before going to bed at 6 mmol/l.

Thank you Mark!

I have never tried to sleep with BG of 6. I just anxious to try it. Therefore, i can't assert that my dosage is high than it should be.

You didn't answer @In Response s question though, when you go to bed at 9mmol/l what do you wake up at?
 
If going to bed at 9 drops to 7/8 in the morning, expect going to bed at 6 with the same amount of insulin to cause a bigger drop, possibly to 3/4. Can you reduce your morning Lantus, or does that make you go high at other times of the day?

I'm type I and my lantus dose is 20 units daily.
 
Reducing the dosage may have the desired effect on overnight blood glucose, but it may also cause high blood glucose at other times of the day. You could also get into the habit of eating something with low glycemic index, like cheese or chocolate , before bed. It should prevent overnight hypos. A third option is switching to Levemir. Because of the shorter insulin action duration, overnight hypos are less likely. Discuss it with your doctor and explain your reasons for wanting it.

I inject all my 15 units of Lantus in the morning, as well as 5 units of Actrapid. The Actrapid,which lasts for about 6 hours, gives me the basal cover I need before lunch. I also eat chocolate before bed.

Any chance you could access a continuous glucose monitor for a while so you can see how your levels go at night? That could answer a lot of questions....

Lantus is supposed to last up to 24 hours but this can change depending on person to person, where you inject, how sensitive you are and how readily your body clears insulin.

You may want to invest in a Libre sensor even if it is for only 2 weeks. A one off £48.29 cost could give you insights about what your blood glucose is doing overnight and you can also observe post prandial glucose to see which foods are better for your sugars. If you can afford it and it is accurate for you then it’s a recommended product by me.

To know if your Lantus is at a correct dose compare BG levels before bed and before breakfast, if they are around the same then your Lantus dose is fine. I have been recommended to keep my blood sugars 6 to 8 before bed but I recognise that we may all have different targets.
