I just focus on hydrating, so that the Epsom Salts can do their thing. They pull water out of your system, so I like to make sure my urine is colorless.
I don't eat anything after having breakfast at 9AM, which today consisted of one envelope of instant oatmeal, with some flax meal and chia seeds mixed in. One time I did a 3 day Water Fast prior to a flush, and it produced the best results, so I try to keep my digestive tract somewhat empty.
Two hours and ten minutes from the first dose of ES now!
