I feel a lump in my thoat for about the last two months so I figured it was time to give up cigaraettes. Also, my head just feels wrong in the mornings. I am now on day 10. Getting so hard. They told me the first few days were the hardest but I thought were actually the easiest. For me, day six and on were beginning to get tough. Never knew how dangerous this product is until you try to stop.
