Re: I really want to quit!! help?
If you're serious about wanting to quit, then by all means do it. Ask your housemates to not smoke in the house. Or at least make an area of the house a smoke-free zone. But don't let their smoking status determine yours. Quitting your own smoking despite the second-hand smoke that you live with is better for you than continuing to smoke in addition to the second hand smoke. It's not perfect but it's better.
When you stop smoking, you will become acutely aware of the stench that permeates every fiber of your house, from the walls, drapes, clothing, brown film on everything from the light bulbs to the TV screen. And with 3 active smokers, it's probably pretty bad. Have your housemates help you clean the place up and maybe they'll get motivated to stop also.
Try spending as little time as possible around smokers or in places where people smoke, especially during the first weeks of your quit. Develop acceptable substitutes to use when you get the craves (and you will). Consider arming yourself with some or all of the ammo that might help you quit - see your doctor for help. Some possibilities include support groups (on the web or 3D), nic replacement therapy, zyban. Studies have shown that combining therapies can raise the odds of staying quit. I believe that, in your present circumstances living with smokers, that a support group would really help you because it would be a group of people with whom you could talk to about what will probably be a difficult quit. There are others in your same boat - i.e. living with smokers - and you could help each other.
You are lucky in that you haven't smoked a long time - however any amount of smoking is potentially harmful so the sooner you stop the better. Best of luck in your efforts.
