Hello i have been burping a lot for almost 1 month and half it comes and goes and a lot of times i feel i want to throw up its really annoying ?

Check for food: allergies or sensitivities. There's something stimulating a burping reflex that shows that something you are eating is not agreeing with your microbiome (good bacteria that helps you digest foods better, or provides necessary enzymes to help with absorption). So do a food diary and see what you're eating at the times when burping occurs, an discuss this with your doctor. You may be surprised!
