I started the slow carb diet last year for new years resolution. At the time I was addicted to peanut M&M's. Took probably 3-4 months to completely rid myself of the temptations to eat a large bag of them. Anyways, in addition to that time period I can remember the first week of the diet feeling the need for a piece of bread. I was like feigning for it. But I resisted. Definitely surgars have withdrawal symptoms, but with so many different foods and drinks out there I do think its an easier addiction to cure than any drug like alcohol or tobacco or even heroine for that matter.
