I personally feel that it's too much to expect of the body to kick carbs AND caffeine at the same time. To some, it's like ripping off a Band-Aid all at once..hurts like heck, but then it's over. I'm more a "pick at it until you're good and READY kind of gal. I figure the refined carbs are more harmful, so they went first. Coffee hasn't caused a lot of grief for me, so I'll keep it until it proves to be a problem for me. Everyone is different.
