raw ginger is helpful - the gingerol supposedly blocks a seretonin receptor that is responsible for experiencing nausea

also, I like to combine ground turmeric, ground ginger, asafoetida, and black salt into a mix and then use a tsp of that in some warm water - that often helps

sometimes chewing some fennel seeds and eating them can help - but I found fennel seeds I grew in my yard were effective, but store-bought seeds never helped me - so maybe it depends on the variety of fennel?

mint is also commonly suggested if there is stomach issues, you can buy these pills at the drug store that have lots of menthol in them, and that can provide some relief
