I had this problem when I started. Bump up your nic level and it will take care of your craving for cigs. Get yourself some really strong stuff like 36mg and the same flavor with lower nic, like 8mg. You can cut the 36 with the 8 until you get the nic level that works for you. Try to keep track how many parts of each you use and you can guess fairly accurately at the right nic level. I'm at 18mg after about a year and it's perfect for me.
