Hey you are trying to quite smoking which is wonderful! It can take time, try not to beat yourself up, many of us have gone through this and it can be a little crazy at times. Do you have any support ? Does your insurance co offer smoking sensation classes? Here is couple of links I found that might be helpful to you?
