Hi doctor! I am 52 years old this year. I went to the doctor for a stomach ache. Every day I take Omeprazol 30 minutes before breakfast, but lately, I have a situation where I often have reflux until I go to bed at night, causing coughing and shortness of breath, making me unable to sleep. So the doctor asked me, I am taking Omeprazol to treat stomach pain but often have reflux at night, how to fix it? Looking forward to your advice, thank you doctor!
