I drink the entire potion in one go: 8 Fluid ounces of olive oil plus 8 fluid ounces of lemon juice. 10 + 10 is the maximum I can consume but this leaves me with some nausea. I use to split the dose but taking it all at once appears to have the same effect. I did gradually build up to this dose which is obviously suitable for my constitution but definitely not for everyone. My advice is stick to a dose that you manage without vomiting and reduce or increase the dose until you achieve an optimum. As you flush you may find that the dose can be increased slowly to ensure the maximum effect.
