Hello, Welcome to Health Care Magic. Thanks for writing. I am Dr.Saddiq-ul-Abidin. I have read your question completely, i understand your concern and will try to help you in best way possible. Your problems can be due to your use of vinegar, or coffee, plus since you have it since just 4 days so it might be some indigestion or pathogen problem you might be having. With simple measure this can be taken care of. There are certain measures you can take which will help you control your symptoms. 1) Avoid bitter sour food. 2) Avoid fizzy, sour, caffeinated drinks, , don t take tea or coffee at all. 3) Avoid smoking and alcohol if you use them. 4) Increase fibre content in your food strictly avoid junk, use whole wheat products , you can even use fibre supplements (organic ones) 5) Eat red and white meat less for some days. 6) Reduce weight if you have more weight than you should. 7) Don t fall asleep or lie down immediately after dinner. have a 15-20 mins walk. Then we come to meds, 1) You can use antacids over the counter for quick relieve like syrup Gaviscon. 2) I would prescribe my patient with Omeprazole or any other PPI they really help. 3) Then my patients responded really well to prokinetics like motillium. 4) I would also ask my patients to take zantac in night if they took omerpazole in morning to add the effect. I hope this answered your question.If you have more queries I am happy to answer.Otherwise rate and close the discussion Regrads.
