Argh....7.8?

My last numbers at the endo were not great...I was sitting at a 7.1 last time I was there, about 5 months ago. My cholesterol was a little high for the first time in my life...so I was nervous about going in this week.
It was a weird appointment.
My cholesterol is back down, good.
But my a1c is up to 7.8. Not so good, and annoying!
I know, I know, I haven't been exercising. So it shouldn't have been a huge surprise, but somehow it was.
She asked me when my numbers seem highest and honestly, it's the morning. But I don't know why! They always seem fine at bedtime and I take 3 units of lantus, then BLAM I'm high in the morning.
She said, as I sort of knew she would, that I may be going low at night, and should cut out the night time insulin. I may be having lows I don't wake up to, and going high after my liver kicks in.
So...I don't take any insulin last night, and lo and behold I am at 6.5 this morning. Not perfect, but waaay better than 10-13 mmol/l I have been running in the morning.
Not sure how to adjust for the little bit I still need to bring it down...maybe 1 unit of lantus at bedtime? Is it even going to do anything?
I'll try it out and let you know.
My goal is to be under 7.0 in September when I go back. This will require:
1. exercise
2. record keeping (you can't control diabetes properly without keeping track of what you are doing...I have set up a logbook that I think might work....based on a couple of models)
3. willpower

Willpower, eesh. I can do it.
