@peterchilds I used to split my Lantus dose to avoid middle of the night lows. For me, it was an improvement on taking it all in one go, but the pump was a significant improvement on that.
You could try the joys of basal testing – setting your alarm for every couple of hours during the night to see what your BGs are doing. This would give you a fuller picture of what’s happening. Or see if your clinic can lend you a CGM for a week, so you can get a proper look over several nights at whats happening while you’re asleep.
