Nausea and Olive Oil. Need your opinion.

I get super sick to my stomach when I put olive oil on my salads. Never mind drink the stuff. I want to do a Liver Flush but I fear the oil will come back out the same way it went in. Has anyone attempted the Liver-Flush while feeling nauseated from olive oil like this? If I end up vomiting, which I'm fairly sure will happen, would it be worth doing anyway? Is there benefit to the Liver-Flush no matter which way things come out of your body? Any opinions on how you think this may turn out for me would be appreciated.
