Bloated for 1-2 weeks during Xmas season

Problem/Goal: Hello, has anyone experienced 1-2 weeks of bloating? Like there’s a constant gas being trapped in the stomach?

Context: So I just arrived here in the Philippines last Dec 20. For 1 year and a half, I rarely drank soda in Australia and I was not used to eating large meals as well. Here comes the Christmas season here in the Phil and 8hrs after I arrived here, I indulged in a buffet meal already. And from the 22nd of December, my stomach starts to bloat, and felt gas trapped in it as I always farting as well. There are days when the bloating subsides but until today, it will still return. I admit, I overeat and I drink sodas and a little beer as well.

Has anyone of you experienced this during holidays were food is readily available and overeat that causes bloating? If so, what shall I do to release this bloating?
