There is something to bear in mind. With dose one and two before the flush potion you are attempting to contract the gallbladder and purge the upper digestive tract. Consequently a strong solution of Epsom Salt is important.
With dose 3 and 4 you are attempting the make sure that all the debris from the liver-flush is swept away and this can be achieve by a lower solution.
As I became more confident with my Liver Cleaning I first reduced the strength of solution from by one third.
Later I took two full doses before the flush potion. Number three was at 2/3 strength and I omitted the final one.
