The original post from Tetsi (sp?) said drink it in the morning. Also, I read some where that the organs are usually wide open between 5-7am. So, it makes sense to me. Though its probably best to do it in the evening. I will be able to flush everything out before work. I think I will do it that way tomorrow.
I've done a flush with ACV in lieu of citrus juice. It was quite different. My best flush, by far, was done with grapefruit juice. But, all I have is lemon juice and orange juice. I use the lemon juice for my lemonades.
