Yeah it is funny how you start to dread drinking some of these things. But I keep doing it because I can't argue with how it makes me feel after. I get the shivers just thinking of the Epsom Salt water.
I usually use a fresh organic grapefruit for my flushes and it helps to get the oil down a lot (did a straight olive oil once). However I didn't have one a couple times ago and used lemon instead and for some reason the lemon was worse than the grapefruit; definitely prefer the grapefruit.
