I assume this is 3T oil and 3T juice. That's almost 1/4
cup of oil and could easily make you sick if you have
anything in your stomach. Most of the flushes require
fasting or Epsom Salts or both to empty the stomach before
taking the oil. Epsom Salts have the added benefit of
relaxing the bile ducts making it easier for large stones
to exit.
At this point, you should avoid eating or drinking anything
until your stomach settles. Either sit up or elevate your
head to avoid nausea.
I'm not a big fan of the gradual flush. Since your feeling
so bad, I'd recommend stopping to let your body recover.
After you feel up to it, try one of the easier flushes.
