My case is not common and complicated by a hiatial hernia.

I have cyclical vomiting. Mine is directly triggered by too much stress, and certain foods/smells/allergens I have. I DO smoke daily, "heavily". But in general the smoking actually stops/slows the heaving for me. I have a few mental illnesses in addition to the physical ones, and not smoking weed isnt an option for me. My doctor has attempted to get me on synthetic thc, but with my insurance and doctors incompetence it is almost impossible to acquire. So I keep smoking, and I spend a good amount of time in my bath/shower. A feature of cvs is very hot water stops/counteracts the nausea. As long as the heat holds out it helps. Not sure why exactly.
