I haven't had that experience, no. I have a couple thoughts, though.

One is that if you're sleeping a little later on non-running days, you might be waking up at a different part of the 90-minute sleep cycle. That could disrupt your body in a way that would reduce your energy at the start of the day.

The other, more likely, possibility is that rather than losing energy for not running, you're gaining energy when you run. Exercise does increase your body temperature during and for a little while after, so maybe the running gives you the energy boost to be awake and aware at the start of your day.

These are just theories; I hope they're useful or interesting to you.
