I am suffering from heavy gastric anytime. That whether I am empty stomach or immediate after eating lunch, dinner, breakfast. Sometimes it reaches a level that I started gaining pain at chest & stomach as side effects. Earlier I was not obeying eating timings, but now whether I eat properly or not, it starts tightening my stomach. after taking meal gas comes out frequently through mouth even. Also dont know it's side effect or not, I am feeling very weak maximum times & feel having less energy for any work to carry out. I am a marketing professional & stay out of station. My present weight is 89 KG.
