My new plan was simple: cut out all snacks and sweets for the whole of January. Then re-evaluate.
If you are a sugar addict, this is really hard and the thought of not being allowed to eat sweets was making me nervous. But I was determined and I managed to push through.
After a couple of days I started to feel better, less tired. This was very motivating and I made it through the whole month.
What also happened: my desire for snacks and sweets vanished completely.
