Hi FL - yes, I crave all sorts of unusual things when I'm detoxing. I'm told it's perfectly normal. It takes a while for your body to adjust to the lack of alcohol levels in it, and your metabolism has to readjust. I've heard this can take months, but that depends on the person of course. When we are drinking heavily, our bodies can't properly absorb vitamins and minerals, so the amazing human body does other things to compensate.
I think it's fine to indulge within reasonable limits! I definitely did, and it does fade after a bit :-)
