Today is my 7th day on Exante, but since yesterday I have felt very light headed and I am also suffering from headaches. I feel the occasional pang of hunger, but do not have a surge of hunger. My breath doesn't smell, but I have a funny taste in my mouth when I wake up in the mornings. The scales have shown a good loss, but the headache is getting to me. I didn't have any headaches at the start, which I know is associated with going into ketosis. I am just wondering if anyone else experienced such headaches/dizziness towards the end of the first week???
