Good advice from BigJane in #18 below about enema vomiting (i.e., not recommended). I’ve taken 2, then 2.5-3, then up to 4 quarts over 50 years of enjoyable enemas, alone and with various exes who enjoyed practicing my kinks with me. I gave myself 5 quarts just one single time almost by accident, which I really enjoyed, but won’t do that much again since 4 q are so enjoyable. I also used to take colonics occasionally from a therapist with a closed system which I also really enjoyed. In all those fillings, even at 5 q, I never vomited nor had the faintest whiff of nausea, saints be praised.
Just as an FYI, in addition to the serious discomfort of vomiting, abdominal pain and risk of GI tract damage including bleeding, enemas large enough to induce vomiting, reportedly 6+ and up to 8 quarts by members here, also have another serious risk. With any cause of vomiting, or emesis, there is a nonzero risk of the GI contents dripping or being inhaled back into the lungs as it passes above the larynx. Normally this risk is minimal approaching zero in an otherwise healthy patient. However if other factors are present, especially loss or diminution of gag reflex, unconsciousness and others, enough GI contents, frequently very acidic from stomach acid, can be aspirated into your lungs and cause serious damage or eventual death (“Aspiration pneumonia,“ et.al.).
If you’re now referring to vomiting from a huge 6+ to 8 quart enema, its not unlikely you’re having abdominal pain as well as internal chest/diaphragm compression from your distended belly making breathing and coughing less effective. In addition, you’re probably lying in a supine or non-upright position during the enema. None of this bodes well for your lungs. Now I’ve taken up to 5 q enemas for sensual and sexual pleasure for many, many years, partly because I’ve always loved the pressure sensations and visual belly distention. However, vomitIng under those conditions can be not only extremely uncomfortable but especially hazardous, so caveat emptor. Watch your volumes and play safely, especially when you have someone else acting dominant giving you the enema.
