I did my castor oil - charcoal experiments between the liver flushes.
Castor oil I took first thing in the morning (2 tablespoons with ca. 200 ml heted milk well mixed).
I did this three times so far and each time the feeling afterwards was even bette than after a LF. However, I must admit that even with Sugar and a piece of banana the taste is not great - not to say awful. The first time I felt the effect after 7 hours, the second and the third time already after two hours.
I have tried Charcoal only twice yet and obviously the 2 gramms I took are too little. Some experts recommend a five time higher dose in combination with glaubersalz (which is not Epsom salt). Anyway afterwards I felt a lightness that even surpessed the feeling following a liver flush.
