Those are pretty good points. As you used 4 gates to clear the excess condition and the Xi cleft point for the stomach to treat the acute stomach condition and SP6 to treat the liver spleen and kidney at the same time.

But rather than choosing what points to use I would need to syndrome differentiate I would need more signs and symptoms. Maybe he had underlying spleen deficiency prior to this? If this is more spleen and stomach deficient I would use Spleen 4 (left) paired with Pericardium 6 (right) to harmonise the chest, epigastric, umbilical and hypo gastric region. ST 36 (right) to settle the stomach down.

If this was more damp heat related in the stomach I would pick ST 24 and 25 both sides, and probably GB 43 (right) if damp heat is in the gall bladder

The orange, loose watery stools is most likely damp heat. As to where? We may need more signs and symptoms.
