Eat last meal at about 4pm
7pm: 1 table spoon of Epsom salts in 8 oz of water (you can get Epsom capsule, which are much easier)
9pm: 1 table spoon of epsom salts in 8 oz of water
11pm: 4-oz of olive oil mixed with 4-oz of lemon juice. Put some honey on your tongue to cover your taste buds ... makes it much easier
upon waking: 1 table spoon of epsom salts in 8 oz of water
