What I do is mix 3/4 cup olive oil with 1/2 cup apple juice shake real hard and drink right away. Then I drink 1/2 cup of fresh squeezed lemon juice. The apple juice and OO (Olive-Oil)
don't mix like grapefruit juice, but it won't congeal like lemon juice. The apple juice will help cut the taste and texture of the olive oil though and makes it easier to get down. I then drink the lemon juice, swish my mouth with water and spit it out and immediately lie down.
I have also gotten good results using apple juice alone. Grapefruit juice makes me very nauseous and I rarely use it anymore, although it works very well.
