The Clinical difference between "retching" and "vomiting"

Over the last 10 years I regularly get vertigo from Meniere's Disease which has multiple symptoms but is basically all of the things you might go through if your vestibular system had developed its own roller coaster fun ride in your inner ear:

It manifests into a number of symptoms including "train station in your ear" which some people playfully call "ringing in the ear" or "tinnitus" which sounds like a plumbers tool.

The grand slam of Meniere's symptoms is vertigo which starts the whole world spinning. At the beginning of the onset it allows you a perfectly reasonable excuse to lay on the floor and hurl chunks. As the disease progresses the effect of vertigo attacks lessens as your bio system welcomes in the hilarity of complete public disassembling and you move from "vomiting" to "retching". We all know vomiting from our first college party where we drank too much. Vomiting is where you stomach empties in an explosive purge. Retching is where the muscles of the stomach push downward and the contents of your stomach remain intact and only a minimal residue of lubricating liquid comes up.

While I used to be subject to hours of vomiting I know have the much improved wretching where, a couple of weeks ago, I was able to drive 30 miles home and pause and wretch every 5 miles taking 3 hours to make the trip. The vertigo has subsided and I can drive as long as I keep my eyes focused on the horizon or about 5 miles down the road.

If you have made it this far, and I have to say I am not sure I would have made it this far, you can understand how relieved I am to be able to maintain some practical manoeuvrability by having the far less violent "retching" as a major improvement over "vomiting".

Now I may be the only one who feels this way but I would rather endure the "retching" performance of Sean Spicer over the "hurling chunks" performance of Sarah Huckabee Sanders as Press Secretary who has a veneer wrap of personality that covers an inner soul barren of human incarnation and exposes an insincere grasping ambitious wannabe who makes the most wooden rote recitation of what she was just fed by Steve Bannon seem like you are back in 7th grade listening to the class idiot scrape metal against the black board.

To summarize:

Sean Spicer makes me retch. This is preferable, by significant measure to Sarah Huckabee Sanders who makes me vomit, hurling chunks across the room.
