My mom smoked (it killed her) when I was a kid. At about 12 or so, I started taking puffs, and liked the way if felt. I was working in a radio station through high school, and everyone there smoked, so then, I was smoking on a regular basis. When I started lifting, I backed off the smoking so I could breathe, but, I didn't quit. When I was in college, doing squats, I decided it was time to quit, and did. I stayed away from nicotine until I worked for Gold's Gym as a sales guy and everyone dipped snuff. I got going on that in 1987, and continued chewing until 2005. One day, as I could tell my blood pressure was to high and I was out walking around the lake shore I told myself I will not let this kill me and I brought my dip can into my place and put it in my upper left desk drawer. It remains there to this day. I was very, very, addicted to nicotine, and had chew in my mouth nearly 24 x 7. When I stopped, I was fidgety for a few days, and craved it for close to a year from time to time. Now a days, I never crave nicotine. Like being fat, or an alcoholic, I don't believe it's a disease but rather is willful self-destructive behavior. If you want to quit, just do it. Then, stay quit. The cravings are a very temporary thing.
A few weeks ago, I tore my right biceps tendon, and it really needs surgery and it looks like I finally found a way to get it done. It'll hurt, BAD, and my arm will be in a sling for three months, but, like many things in life worth having you get through it.
My mom spent the last 2 years of her life on an oxygen machine. I watched her friends die from lung cancer. Would you do that to yourself? A little TEMPORARY discomfort is nothing. The saying that's been used around here lately is "man up." That's just what you need to do. Sometimes shit is hard, but, we do it because we know it's the best thing.
My friend, Dave, who retired at 42, after 20 years as a pilot for TWA, died at the age of 59 from COPD. Until almost the very end, Dave wouldn't stop smoking. Don't be like Dave. Don't abuse yourself like that.
flex89 / Logan is a type 1 diabetic who lives with me. Dealing with nicotine withdrawal is nothing like dealing with diabetes daily. You just need to man up and get 'er done.
Just like a drunk shouldn't be around drunks, or a fat person around fat people, you need to stay away from situations that trigger your bad behavior. After you've been quit for a while, you maybe can re-enter those situations, but, at that point you could very well not wish to be around unhealthy people and the stinky folks and have no desire to go back there.
The American Lung Association is a great place to start.
