Lantus problems and going round in circles

And on and on and on...

When we began writing about our experiences of living with Diabetes it was, at least in part, in response to a nasty overnight hypo brought on (I suspect) by the action of Lantus glargine. From some reading I have done since it appears I am not alone in this. That there are other people with diabetes using Lantus and injecting their dose at night time (recommended by the manufacturer and for most people the best option) who find they sometimes go low overnight, or wake up low in the morning.

One of the difficulties in managing diabetes with MDI (multiple daily injection) basal-bolus is that if you don't get your basal (background) dose correct then everything else becomes incredibly difficult to manage. You have no firm footing on which to start your day.

I think the late-at-night injection timing is suggested because it puts Lantus's onset period (perhaps an hour two until full strength) at a time when you have finished eating for the day and are usually if not actually asleep, then pretty much at rest. When I moved my injection to the morning, though my overnight levels were suddenly very steady and reliable, I had problems with high blood glucose spikes after breakfast. In response I began to split the dose, morning and evening, having a little just before bed, and the rest at breakfast. My hope was that this would spread the activity more evenly over the day. Sadly though, after a few months I can see that this has caused more problems, and not really solved anything. I found I was waking up low again, or waking slightly clammy having gone hypo overnight. On several occasions my liver then took matters into its own hands and began dumping glucagon into my bloodstream as it's own emergency measure. I would wake high, inject rapid-acting insulin and wait until my levels dropped before eating breakfast. After 2 hours or so I would give in, my levels still stubbornly high, eat a fraction of my usual breakfast and wait to see how things were going at lunch. Not only that but if the smaller Lantus dose didn't send me hypo overnight, then it had run out of steam by breakfast anyway and I was heading for spike central again after breakfast. Smaller doses you see, tend to act over a shorter time. With no Lantus hanging around, and anything from 15-45 minutes for Humalog to get going even a fairly low GI breakfast was going to cause problems. What my neice might describe as an #epicfail.

So I've gone back to Lantus in the morning. Suppertime and pre-breakfast readings are more constant. The post-breakfast problem still exists, of course, but at least I've lost the overnight hypo and liver-dump double whammy. Last time I didn't spend much time experimenting with the timing of my breakfast bolus (rapid-acting) doses. My hope is that with enough time between injecting and eating I might be able to stay out of the teens between breakfast and lunch.

Maybe.
