Yes. I don't like chocolate, jelly beans, soda (well sometimes), etc., but my body metabolizes alcohol like a sugar, so sugar emulates that insulin spike that you'd get from alcohol. I actually employ sugar in my evening snacking as a way to curb cravings in early detox. Then I cut back on it.
I get tired for a while. I remember my first stint of stopping and the quantities of coffee I was eventually drinking. It was a lot. I need to remember to back off on the caffeine too, though in early detox, I avoid it because it triggers a craving if I don't eat enough. The tiredness comes from your body trying to heal and re-calibrate.
