I used to vomit after drinking milk or food with milk acid reflux they said what should i do? what medicine should i take?

Vomiting or regurg?: Big difference--if regurgitating foods as you describe (that promote gastroesophageal reflux), then you probably are describing gerd ; diet modification (; acid reducer) is in order. If you are really vomiting as often as your question implies, then you have a bigger problem that warrants medical evaluation (checking for ulcers, gallbladder disease, pancreatitis, gastroparesis, pregnancy, etc.).
