I'm no expert but I'd say try it. You need to find something that works for you. I've done the cleanse twice with grapefruit juice and for me it tastes so much better than the Epsom Salts that I look forward to the oil/juice mixture.
I can't stand the taste of it to begin with, and after my second attempted flush, it made me sick to my stomach as I was trying to drink it down. I can't even stand the smell of it now - it makes me queasy.
