This uncomfortable feeling is actually quite familiar. I think I experienced it during Ramadhan month, albeit not as bad as now. I suspect it has something to do with immediately sleeping after meal.
Moral of the story:
- Never Ever Immediately Fall Asleep After Having Meal
- If you really need the sleep, try not to fall-flat in the bed. Sleep in the sofa, or use multiple pillows to make the head in elevated position compared to the stomach
- Coffee, or any acidic drinks/foods will amplify the uncomfortable feeling.
So far I did not take any medicine, nor I know any treatment to alleviate the discomfort. The discomfort will be gone by itself in 2-3 days. As long as you didn’t repeat to immediately sleep after meal.
