olive Oil and gag reflex

I have done 1 flush with great success. My wife had her gall bladder removed 3 yrs ago. I recently posted a message asking if you can do a flush with out a gall bladder and the answer is "yes". I told her she should do a flush, BUT, she has a bad gag reflex and she says she could not handle swalloring the olive oil. Is there any other means to force the flush?

Thanks,
