Ham,
Nolaq is right. If you wait until you're comfortable, it'll never happen. The things you have to know straight off the bat:
1. It will be hell. You never hear a drug addict say "Wow, that was a breeze!". What you hopefully hear them say is "Thank God I did it. It was the toughest thing I ever did, but I saved my life." Same goes for nicotine, because it's a drug and we're addicted to it.
2. You're right about the oral fixation. Different things work for different people. I chewed jerky and am now transitioning to coffee grinds. After I hit 100 days I'm hoping to keep some fake around just for emergencies. But others never touch it.
The moral of the story: by the time your birthday rolls around, now you'll have one day fewer quit. And if you don't do it today, it'll be the same story tomorrow. And when your birthday gets here you'll still be a dippin mofo! And then, well hell now you don't have that deadline anymore so you can just do it whenever, right?
WRONG. We're here for support man, but you gotta take that first step. Let us know when you're ready.
