Tips to contain sudden gas flareups?

I’m getting treated with berberine and oregano and while the bloating has gone down a bit it is still present after over a year. it’s better now but sometimes i get these flareups where my lower belly will feel congested and heavy even when i haven’t eaten and skipped a few meals out of bloating. i also take charcoal sometimes and glutamine in the morning. but these flareups randomly happens sometimes especially at night. it feels like trapped gas, inflammation, maybe constipation. does anyone know how to ease these symptoms when they come up?
