where people touched by diabetes help each other.

I keep getting low blood sugar when I'm sleeping. Really frustrated about it. Any suggestions ?

Are you using a pump or on injections? Is there a most common time of night they happen? (Mine are generally 2am, or 4am, and those have different causes and prevention, so it's not as arbitrary a question as it sounds!)

I use injections . It always happened between 2-4am. I want to lower dose of insulin, but my doctor asked me better not to.

Do you consider "insulin on board" from previous doses when you give a correction dose?

If it were me, and assuming I had last taken any fast-acting insulin before 9p, I would start by lowering my basal insulin (lantus/levimir), starting with the smallest increment I can- usually 1/2 or 1 unit, and reduce by that amount every day until the lows stop.

If my last fast-acting (humalog) dose was later than 9p, whether it was for food or a correction, I would again reduce that dose by the smallest increment possible, and repeat until more than 50% of my nights didn't have a low.

Adjusting either though, can/will have trickle down effects so if you lower a once-a-day basal dose that means other times in your day are going to be higher and you'll have to deal with that as well. I hugely recommend using one of the available dose calculators, I've been happy with both RapidCalc and PredictBGL as apps that do a better job faster than I can do in my head, and make it easier to adjust dosing when needed.

Check out the books Using Insulin by John Walsh, and Think Like a Pancreas by Gary Scheiner for more ideas on when and how you should adjust your doses for best results!

I just ordered Think Like a Pancreas. Does it help with spikes?

Thank you so much Skye! I use lantus every noon and nuvalog before eat. I'll download the app you remembered to see if it will help:)

@Charlotte, I found the book to be really useful because it gave me enough information to be able to make a better informed decision about the actions I was choosing, which helped/helps me decide if I'd rather prevent or treat a given situation. For me, preventing spikes hugely depends on my willingness/ability to inject about 30-45min early, and pick better carbs, but I learned that by doing a lot of trial and error after getting some good advice out of the book.
