I continue to drink apple juice until about thirty minutes before the first Epson salt drink, and I make the drink with apple juice most of the time. I actually have fewer problems when I continue with juice. It helps keep my hungar at bay and blood Sugar levels up. I never drink juice or do more than sip water after the second ES drink. To prevent violent nausea and potential vomiting, my stomach needs to be empty. Others might have different experiences, but this is what I must do.
I try not to eat after 2:00, once again to insure the stomach is empty when drinking the oil/juice. I tend to have rather slow digestion sometimes.
