Keep away from your triggers, coffee/alcohol/stripclubs, and all that. Also keep in mind you are taking away days at a time with each pack and instead of just dying of old age you will probably have a slow and agonizing death with copd or lung cancer. I tried to quit several times, even told myself in 2012 if I didn't quit the works would end lol. I did that for 18 months then sure enough hung out with smokers and tried to prove I could have one. As you read above you can't and fought it on and off until a year ago. I just had to muster the will power to take my life back. Googling images of smoking effects (lungs, body, ways to die, trach tubes) also helps. You can do this. It will also help your reef tank by keeping out unwanted chemicals, just like second hand smoke effects kids.
