Not because you are diabetic but for some other reason. As the poster above suggests, commonly if your sugars are high or dropping this interferes with sleep patterns for sure. So its worth while checking before you go to bed. Another thing that sounds crazy but I've seen time and time again is when it comes to injections, at certain moon phases the insuling is absorbed more or less absorbed. So that's also worth noting. For example during full moons people tend to not be able to drop off as normal too.
