Hi Lizzie,
Just want to say that you're not alone. I'm afraid I don't know how to fix it, though
Since I've started pumping, I can now see why Lantus gave me such grief. My basal needs slow down at around 10pm at night, get slower still at midnight and my body needs almost no insulin at all for a 3 hour period of the night. If Lantus were to cope with my needs during those 3 hours, I would only be on 1.8u of Lantus per day (assuming a flat 24 hour profile as you are assuming). Early hours of the morning is when I need the full whack that equates to 13u per day of Lantus.
If I used to put in the full amount at night, I would have to feed my face before bed to cope with the large BG drop in the night. Going to bed with a BG below 10.0 (180) was not sensible. The alternative of splitting in me caused my daily bolus shots to lose potency. I cannot really get my head around why this would be as basal testing still claimed that all was well. What I do know is that splitting Lantus sent my control so far downhill that I prefered the huge BG drop overnight.
I'm afraid I don't know how best to fix it on MDI. That's why I went with the pump. I really do wish I had looked into it years ago; whilst most of my basal problems appeared out of the blue quite recently, I'm now starting to realise that I haven't slept properly in years. The quality of sleep I'm getting now is a huge contrast to MDI...
If you do wish to consider a pump, call your clinic NOW. It can be a long process which usually starts with seeing the pump nurse at clinic. You can get that bit done now rather than waiting to see your guy in October.
Even if you don't want to pump at present, they WILL get you in for some one to one advice before October if you are having problems. The regular appointment is just a check up and if you need help, you need help. Call and ask nicely. If that doesn't work, demand.

And then a little pump floats by
And now my pants are filled with tubes
That tangle all around my.... er .... knees
The hours I'm hooked up? All twenty four
And that's it for now until evermore
But I disconnect for up to an hour
For wonderful fun (and sometimes a shower)
And when I 'suspend' it, it plays Barry White
And my wife knows she's in for one heck of a night
But only an hour of that night is with me
As an hour is all I'm allowed now, you see...
