Totally agree with you.
I know that I sleep poorly walking Caminos, (yes, all 20+!) for whatever reason that may be. I am consoled by the fact that I sleep perfectly when at home and so I accept the broken nights. In April I took the experience to the next level:
I was staying in the municipal in Arzúa, joining the Francés after walking the Primitivo. The albergue was packed with young Spanish in a partying mood, hoping to reach Santiago by Easter .10 p.m. curfew? Don't think so. Across the street locals were chatting till about 1 a.m., then began the Flamenco singing! To top it all off I was sleeping between 2 snorers, me awake from 9:30 till 2 a.m. I finally gave up the prospect of sleeping and actually got up and walked to Santiago at 3 a.m.
By 6:30 I had coffee in Pedrouzo and at 10:30 I was standing in front of the Cathedral after a 39 km stroll 
.Granted, this might not be your cup of tea but it was an interesting experience. The previous night had been a full moon so I rarely even needed by head lamp. Just me, the moon, the occasional barking dog, birds chirping and frogs...hmm, what do frogs do?
