Headaches are part of withdrawal/About withdrawal

Got into bed last night and, bang, a headache started. All on the right side of my head and running down towards the back of the right side of my head. Blah!

Today, I've had more headaches in the sense that my head mildly hurts all the time. Gillespie includes a list of symptoms you may have when withdrawing from an addiction but everybody is affected in a different way so it's hard to generalise. He says that, when he went through withdrawal, he had "a perpetual (but not severe) headache."

Eventually, I'll be free of the desire to eat sugar. Yay! Completely free. Apparently, the deisre will just vanish. It sounds unbelievable but will happen.

He explains how addiction works by "developing a reward-and-punishment system. As soon as you stop taking the addictive substance, its euphoric effect begins to decline, creating a mild depression in the process. It feels like an emptiness, or even a boredom...makes you crave the hit that you know will relieve it. Eating sugar in moderation for the rest of your life is the worst of all worlds. You're not eating enough to truly relieve the craving (and so noreward for you), but you are eating enough to maintain the dopamine response that keeps the addiction circuit alive in your brain."

That's why you must go cold turkey and can't go along, hoping to cut back. "You can't drift into stopping an addiction. Because your lust for sugar is a chemical addiction, there will be a chemical withdrawal. And that is not going to be pleasant. You have been addicted to fructose since before you could talk, so getting unaddicted will take a modicum of effort...what it will not take is willpower...You will henceforth not touch a food containing sugar. This will not be fun, at first. Bur starting is half the battle. Hold the line. There is no moderation. You have stopped poisoning yourself. If you can just get past the next few weeks of danger, you will enjoy the health sugar has sucked from your life to date."
