ELI5: why do we get a horrible feeling right before we puke and feel better after doing so until "that feeling" starts to build up again ?

When your body needs to vomit it will produce chemicals to make you nauseous making you want to puke. After you vomit dopamine is released making you feel better. Your body rewards you for getting rid of the toxins in your body.
