Is lemon / lime allowed during the day of liver flush prep?

I've done quite a few years of Liver Flushes the Andreas Moritz & Hulda Clark way.

Now since I've done a couple of Master Cleanses (10 days of only lemon, molasses & cayenne), it dawned on me that that might be an easy way to "eat" the day of the liver flush.

BUT I've also heard that lemon & lime are unique in that the citric acid stimulates bile flow! So if that's true, should lemon and lime be avoided the day of the Liver Flush just the same as we avoid protein & fats the day of the liver flush?

Thanks!
