Nope, don't mix the oil with the Epsom Salts . They're 2 seperate drinks. THe olive oil is mixed with lemon juice, or grapefruit juice is also suggested. It has a more pleasant taste and may mix better with the oil. Of course, you're right the oil won't mix with the lemon juice. So if you're using lemon juice, don't mix them, alternate taking the oil then some lemon juice to get it all down.
