I have done three different flush types. What works best for me is NOT to use Epsom Salts . I usually eat light or juice fast when I flush (I am flushing tonight, actually...maintenance flush....I can tell my liver is acting up again). I take the oil/juice mixture at bedtime....I don't worry about getting into bed right away and laying still or anything. I drink a 10 oz. bottle of magnesium citrate upon waking, to replace the epsoms and get my bowels moving.
Having clean bowels during flushing is vital as you will break out if you don't do an enema or get a colonic or do something to clean your colon out. I got major breakouts on my 3rd flush because I didn't know you should do that.
