Time to quit

Hi I am 35 yrs old, been smoking since I was 13. I never tried to quit eversince and then one day I went to see my gp because I was having twitching eye and then he asked if I still smoke and I said yes and I paused for few seconds and said to him, can you help me on how to quit smoking? The doctor smiled and said YES ofcourse and he recommended Champix but told me all the side effects and the one I didnt like was the 'nitemares' for first week I was doing all right, I get so sensitive at home but I told my 3 kids to try to understand me and they were really good. my husband just laughed at me when I told him that I am taking champix, he doesnt believe that I will quit smoking but I told myself I will do this for my kids, my self, family, friends and people around me. I'm so glad that theres medicine that helps people like me to try to quit smoking, I am on my 14th days now and I know I can do this. I quit on my 8th days and after couple of days a friend came over and offered me cigarette, I lighted up and it taste disgusting and smell really bad so I throw it. Now, I get to spend more time with my kids, I dont hear them whining that I smell cigarette and great feeling to see them happy knowing their mum quit smoking
