I am a 55 years old man, weigh 97 kg and am 173 cm tall. For the last one month, I have severe acidity problem due to which I am unable to sleep at night. I experience chest pain and irritation in the food pipe. I used to go for night walk daily for an hour or so but due to uneasiness and tiredness after work, I have left it. I have consulted a doctor who has prescribed these medicines - Parit, Rantac, Beplex forte and Unienzyme. Am I on the right medication? Is there any permanent cure to acidity?
