I can relate to "fantasizing" I had a dream last night I was at a buffet and headed straight to the "sweets table" and gorged myself there..lol It is common for many to be achy for awhile when starting low-carbing....your body getting rid of toxins. I was along with having a headache, tummy upset and being real grouchy...lol. Im sure it will pass. Are U taking many vitamins? Ones that may help is potassium, calcium-magnesium. Drinking lots of water?
