Lots of Lows After Basal Changes

Yesterday my doctor suggested some basal changes.  As I said I was going to, I implemented the overnight basal change only.  So here are the results, comparing the night before I made the changes and last night:

The number one problem is that immediately there are a whole lot of lows, so the exact change that he suggested didn't work.  But the line looks a lot straighter, so there is definitely merit in what he suggested - I'm just going to have to tweak the numbers a bit.  I'm hoping that if I lower the basal a touch it'll keep my glucose in the blue all night.
