I went through this a few months ago. I’ve had a huge sugar addiction, mainly through chocolate, for years. I decided enough is enough and stopped eating it . It seemed to take ages to get out of the sugar “slump” I felt I was in. No energy and a lack of interest in all my active hobbies. I’ve now come out the other side and yes I still snack on the odd bar but it’s so rare now as it all tastes false and chemically flavoured. I’m now eating more fruit and drinking loads of juices etc which have changed my taste buds for the better.
