Throwing up daily

I throw up everyday at least 2-3 times but it’s more like 5-6 times I don’t know what to do I am on zofran and phenegran and still throwing up. This has been going on for weeks now and I’m so tired I could be perfectly fine and then suddenly nausea will hit and the vomiting starts I have tried sour candy, saltine crackers, lemon, preggie pops, ginger ale and nothing helps 😢
