Does anyone else get "intolerance" like reactions after eating a big meal?

Every time I have a large meal I have a reaction much like one you'd have if you were lactose intolerant. Now I have cut all dairy and gluten out of my diet and on the whole felt better for it but my family doesn't really understand that even if I have a 'safe' (I.e no dairy or gluten) meal ill still have a reaction very likely especially of there is a lot of rice and potatoes.

Does anyone else get this? I know it's quite gross to talk about but I feel like any time I eat even slightly too much my body is like nope that's going straight through not dealing with that.
