indigestion
"My mother has been sick for years... when I say years... I mean I'm 39 I can remember her not being able to keep food down when I was a teenager. She's had every medical procedure, every treatment you can imagine. She's on medication for other illness (antipsychotic meds) but nothing has ever worked for her. 

Finally, I suggested maybe you can try Zantac... to date, it's been a full month without her throwing up her food! Whatever is in this stuff... we truly believe it's gonna save her life! Thank you."
