Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for you as follows: 1. I would like to know more about your symptoms like whether you have recurring nose allergies, nose obstruction, sinus symptoms, stress, etc. From your given history, I would think of 3 possibilities: a. It may be obstructive sleep apnea, usually due to nose obstruction due to allergic rhinitis, sinusitis, etc or some other obstruction in upper respiratory airway. In that case, I would suggest you to get examined by a ENT specialist who will examine your nose from inside and may identify the cause. b. It may be gastroesophageal reflux causing choking at night. As you have acidity, this is also a possible cause. In that case, I would suggest you to take an antacid like ranitidine daily before meals for at least 4 weeks. c. It may be night terrors, especially if stress is a problem for you. In that case, relaxation and consulting a psychologist may help you. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health ahead. Thank you & Regards.
