When I was attempting to wrestle Lantus into submission I tried a split (but the waking hypos returned after a few weeks) and ended up, as others have said, shifting Lantus to breakfast time. When taking it at approx 10pm the mini-peak of activity that Lantus often shows at approx 5hours post-injection was exactly times to collide with what I can now see it my need for less basal. Breakfast lantus did properly mess up readings after toast (since it was still in onset and DP was wading in) but I tried to beat that down with extra rapid and a 45 minute delay before eating breakfast.
Infinitely tweakable basal profiles vs my ongoing struggles with Lantus were a big part of my decision to go for a pump. My morning readings have never been better since the switch.
