 You have to also understand that your body may not want the drug to cause you to lose weight. If your body does not want things slowing down, it's going to fight the drug. And when you burp or you vomit or you throw up, that's your body not tolerating the drug. That doesn't mean the drug is working. I know some people say, well, I want to make me so nauseous that I don't even want to eat. Yeah, that's not sustainable.
