Yes, he eats morning and night, but not freely. I normally am getting up for work around +9 most days. I try to grab a test then if I can remember with my coffee starved brain. When I have been able to test during his PM cycle lately, he doesn't seem to be going very low. Back when we were getting a few greens, he was dropping pretty low so I had to watch him and test him through the night, but now he seems to be higher than his AM cycle.
