Thats right, I tried to give up because I thought I was bored of smoking. This was 10 years back. My friends and family were always telling me to quit so I tried it. I happened to try to give up just as my current wife asked for a 'trial separation' and I started again soon after. I think the whole process from giving up to starting again took about 4 weeks. I didnt use any pills or medz, I just convinced my body that the brain say "NO!", and parented myself through the cravings. Then I just forget to smoke until I didnt smoke.
Since that time I have not entirely enjoyed admitting my love of smoking in order to smoke in peace, but rather than fight family and friends I decided to just love smoking, and now I dont care what they think as long as I dont go about reeking of cigs; which is a no-no. Apart from that I have no intention to give up again.
