It is much harder with sugar. I had to trade the process sugar for the fruit sugars first. It has been difficult. I had to because of a hormonal imbalance and fibroids, but it was so hard. What I did instead of eating cake, pie, and cookies is dates. I would take dates grind them in the food processor with almonds and cacao it tasted lie a candy bar. Or I would process almonds, dates, and freeze dried strawberries tasted like strawberry cake. And yes, there's smoothies and banana ice cream. For the banana ice cream I would blend frozen bananas and a 1/4 cup of pine nuts, and dates. I fold in my favorite fruit such as dark cherries or I add cacao. and a bit of maple syrup.
Nowadays it's a little less day by day. But cold turkey, man I would be a crazy "biotch!"
