I like early rides too. Mainly for lower temps and less traffic.
But if I eat a big breakfast like that, it puts me to sleep.
Sadly (and funny), much of my day rides are planned around places to take a leak. I'm not a fan of hitting 711s and using their facilities without buying anything. But I will walk around behind their dumpsters, this clump of trees, that deep drainage ditch.
One particular convenience store out in nowhere I hit almost every ride has no public facilities at all, but does have a portacan around the side. It's the filthiest nasty portacan I ever saw, and never apparently cleaned (in 20 years). I leave the door open to let out all the flies and improve the odor. But I only pee there; IF I had to sit, I'd go in the woods like the bears.
