Jeremy,
Don't wait till tomorrow. I know that sounds weird. You've had nicotine, so why would you post a Day 1 now? Here, we generally say Day 1 is the day you quit. What you're promising when you post that Day 1 is that you will not have any for the next 24 hours.
Make that promise now, because it eliminates the possibility that tomorrow morning you'll say "well, just one more day." And we all know how that goes.
Oh, and if you haven't already, flush everything. Smash the gum, wrap it in a moldy vegetable and throw it in the bottom of the trash can. There's no longer any "Just In Case" stash. You are quit now, and you'll be quit for the rest of your life. So embrace it my man, it's fantastic.
