I have hyperthyroid and I am under medication with carbimazole and Metomorpol. Also had acid reflux issues so was under Omeprazole for as i didnt see any symptoms after a month stopped taking it. However started getting symptoms after 4months recently (1month back) instead of medicine i was taking apple cider vinegar with warm water in empty stomach. Though situation was better yet had symptoms on and off. So started taking omeprazole from past one week. However from past three days am getting frequent burps and dry mouth though consuming warm water (boiled with cumin and ajwain) often. Occasionally feeling congestive chest or upper abdomen(right side) (feels like trapped gas). Especially in night have been waking up frequently (within 1 to 2hr) due to dry mouth and thirst so as i consume water i get burps and don't fall asleep for short time. When I wake up i feel palpitations (kind of stressed / anxiety).
