After my smoking blog earlier in the week I heard from people who have kicked the habit. I thought you might be interested in reading their comments and suggestions.
Go cold turkey. Just stop lighting up.
Don't put pressure on yourself to quit. Just try to go one day without cigarettes.
Tired of coughing, "I stared at the cigarette, crushed it, and never looked back."
Use the nicotine patch. It helps with the cravings.
Fair warning - I'm going to vent about a topic that not everybody is going to agree with. I would have to guess that at least once a day I see someone throw a cigarette butt on the ground or out of their car window. Sorry if you disagree, but it's litter, plain and simple.
