IMHO..Try Almond Oil... Maybe it will work.
Hi:
I have just finished my 10th flush. And I have experimented with 4 oils. Olive/Almond/Coconut & Macadamia.
I can totally understand that vomiting can be gross and uncomfortable. I have puked in 70 % of my flushes.
I really appreciate that you introduced and encouraged your old folks to flush. And admire that they tried it. Actaully my mom is sick with High BP and
Arthritis and I am asking her to flush, and she says NO WAY can she drink 1/2 cup oil.
Anyways, as far as my opinion of oils go, ALMOND OIL is the best as per that taste goes. And its effective too. I released some very big stones when I drank 1 cup of Almond Oil on my 8th flush. Almond Oil has such neutral taste and so light that drinking it down is very easy. I found it in Health Food Store.
And of course, GFJ should have no pulp. Sucking on a mint candy after drinking the oil helps. So does holding the nose while drinking the concoction.
Good luck.
