The olive oil and grapefruit combination will clear the gallbladder and dump the bile which is why your tummy went off. When you clear the gallbladder it allows the liver to flush into the gallbladder. Most people have some trouble with the full dose, you might try 1/2 the amount for a day. This works as a mini flush to prepare for the full flush. Also consider that it must be flushed into the colon and will cause problems if the colon is not cleansed first.
