A pleasure reading your response...however, and even though I try to be, through reading and learning, I am in no way an expert, like so many claim to be...LOL But, nausea is a chemical imbalance within the stomach, which when disrupted, gives you that sort of heartburn and the need to get out what is causing that imbalance.
Chemo, for cancer patients, also causes a chemical imbalance as well and affects the body's immune system and more.
The reason I appreciate your response is you touched on something that I may need to further research.
Thanks.
