Hi Chexy,
could not find the new post you referred to, so hope you read this.
If you cannot find organic lemons, then use the juice of regular lemons. I this case do not use the skin, as regular lemons get coloured and waxed, all toxins for your body.
At the following link there is another similar preparatory version of what I did:
www.curezone.com/cleanse/liver/Gallbladder_Flush_7_day_program.asp
What is important is that on day 7 have nothing with fat or oil at all until the flush. Also not to eat or drink after 2 p.m. if you are planning to drink the oil/juice mix at 10 p.m.
Hope this helps.
Good luck!
