Thanks for providing more information.
Sorry for late reply and inconvenience.
As per your description,your symptoms suggest the possibility of Viral gastroenteritis.
And in most of the cases,infection resolve in a week.
Now as you have bloating,belching,lethargy,heartburn so with your current symptoms i recommend you to continue Gas X and start metamucil and probiotics.
Even you can take OTC Prilosec to relieve heartburn.
You should take oral rehydration solution as well.
Most likely you 'll be fine in next 2 days.
If your symptoms'll persist then consult your family doctor.
Hope this helps.
