I am now into week 6 of the 12 week plan and getting good results. However this last week I have been getting severe mood swings, from positive and energetic in the morning to flat and wondering why I am bothering in the afternoon. I don't think it is low blood sugar as it continues even after I have eaten. Has anyone else experienced this? I am hoping it is temporary, and to avoid temptation in the meantime I have banned chocolate from the house and only go shopping when I am feeling positive.
