Numbers before bed

My doctor wants me to test 2 hours after eating, but I often test earlier because I am curious. It turns out that my blood sugar drops a lot quickly between the 1 hour and 2 hour mark. I'm going to bed now and my number was 95, but it was 136 about 45 minutes ago. Is 95 too low for before I go to bed? What do you guys usually target for before bed? A lot of times we eat too late to fit in a snack before turning in.
