The thing about eating something your entire life is that you have no period of feeling better to compare it too. When I first decided to devote a month to cutting out carbs & veg oils, the withdrawal was truly horrible, but by the end of the month I felt better that I had ever felt in my entire life. I was sleeping better, was so clear headed & free of little aches & pains that I just never went back. You don't know what you're missing until you actually experience it. 

 so true. i can think of an even worse paradox which i am struggling to even articulate, which is alcohol. where there's even a phrase for feeding the problem as a symptom in "hair of the dog"...
