I’m currently suffering with a nasty sickness bug and was wondering why my mouth fills with saliva right before I vomit?

Supposedly “hypersalivation” happens because the two parts that control vomiting and salivation in our brain are so close to each other that cascades(“waves”) of excitation regularly happen and spread to nearby “circuits”, especially accompanying the signal cascade that forces your body into convulsion and vomiting.
Due to the high acidity of our stomach contents, this also serves to protect the mucous membranes so there might even have been evolutionary pressure selecting slightly for that kind of wiring.
