SKHerb, I'm hoping you are well out of the cravings now (sorry I didn't see this yesterday!), but I think the third day is the hardest. Some people have reported feeling poorly up to day five, but three days is my personal detox time from sugar and day three is the hardest. It's like your addiction is inside you, realizing it's about to lose and it puts all its effort into one last push to get to you eat sugar. How great you feel after you defeat that addiction, though! It's totally worth it.
I concur on water, eating gum, exercising, and anything to get your mind off it! I let myself go play a junky computer game just to get my mind on something else.
