As an aside

I believe the number of episodes of reverse peristalsis I have endured in the past year surpasses the number I suffered for the entire decade previous. Including those episodes induced by collegiate.... overindulgence.

I expected pregnancy would permanently change my body in various ways, but this was... not an anticipated permutation. It's especially ironic since I never actually engaged in the activity while I was pregnant.

It would seem my stomach got stretch marks on the inside too.

One group of interneurons activates excitatory motor neurons above the bolus - these neurons, which contain acetylcholine and substance P, stimulate contraction of smooth muscle above the bolus.
Another group of interneurons activates inhibitory motor neurons that stimulate relaxation of smooth muscle below the bolus. These inhibitor neurons appear to use nitric oxide, vasoactive intestinal peptide and ATP as neurotransmitters.
