Still hit the 18 hour wall. Could do it pre-op. You’d figure 16 months out I could, too.
I’m thinking at this point it’s something to do with the ghrelin-leptin relationship. I will commence further research. Sadly, most I’ve found is about day-long fasting only, i.e. Ramadan, and all of it involves carbage later.
Not a true fast, but I will probably just do butter every four hours and we’ll see how that goes, next time.
