Acidity reflux. Fix it permanently?

I've had major health issues because of acidity in last 10 years of my life. Once I was down with stomach pain for almost 24 hours and nobody knew what to do with me, acidity was severe and the Dr they took me to, he declared me pregnant because he detected some kind of ball in my stomach. Literally he was the messed up Dr. and I was just 19 years old then, but in the end it was acidity which calmed down on it's own after many hours. Having said that, I often end up in emergency room crying with pain in my head and an uneasy stomach, and it's always acidity. After many years of pain I've finally realised there is one quick remedy for my acidity, Vomiting. It helps me instantly, but sometimes vomiting once leads to a series of them which leave me dehydrated and then again in emergency room. I am sick of being helpless of acidity, no matter how much I watch my eating patterns it always finds a way to come back. Can anyone please help me rather fix it permanently?
