Yeah I reckon it will settle. I eat really high fibre mostly and coffee. I don’t have a strong coffee and then set off on a five km walk (learned that the hard way) but it does settle after a couple of weeks. I find eating consistent meal times helps.

When life gets ahead of me and I start slacking on the fresh veg + pulses + brown grains there’s always some adjustment time.

Can’t tell you if no coffee is better because you can prise the coffee out of my cold dead hands.
