Surely by adding the lantus it must push it even further south throughout the day?
It can have that effect if the dose is too high. Lantus is your background (basal) insulin. As @Inka says, its job is to balance the glucose that is trickled out by the liver 24/7 to keep things ticking over between meals. If your dose is right, you should be able to skip a meal (or sleep through the night) and your glucose levels should stay steady only rising or falling by +/-1.7mmol/L.
The snag is that the ‘right’ dose can change through the year. And of course some days you are more active than others, or might have an illness, so your basal needs can change.
It should be the bedrock on which all your meal doses sit. But if you have too much, your levels might be generally trending downwards, and meal doses might over-reach. Or if it’s not enough your levels will generally be trending upwards, and some of your meal doses will be covering the ‘missing’ basal, meaning your rises after meals might be higher, and reluctant to come down.
That’s why forum members find it so important to get their basal dose as ‘right’ as possible, and to keep adjusting it month to month, and year to year.
