What do you do about food and drink on long stages?

Tortilla Española, Camino de Santiago

The question was:

How do others cope with the lack of food and drink places on many of the Caminos?
Having just walked from Toulouse, where there seems to be even more villages without shops or bars than there are in Spain, and I know there are many in Spain, I found I was carrying food and drink for the day, emergency supplies in case there was no food in the evening, supplies to cope with Sundays and Mondays!! It was only when I stopped that I realised how heavy my food bag had become. Does anyone have some secret coping mechanism? how do others manage?
