I've been contemplating the idea that there might be more than one cycle involved. Several people report abstaining for a short interval, long interval, and then short interval. I realize we probably don't know the answer to this due to lack of research.
That lead me to think there might be a brain nutrition issue. It must be a lot of work for the brain to remake itself and constantly control the urges of other parts of the brain. Does the brain run out of steam at some point after a longer period of abstinence and then need some time to build back up? Can some kind of nutrition help? I'm guessing this is why mediation helps (brain stretching), but brain athletics might require different food, vitamins, etc. Has anyone toyed with nutrition issues and found anything that makes abstaining easier?
