Don't Do It!!
This is your shot..
If your quit starts at midnight and you are drinking and smoking right up until 12
you might just say "well what the Hell. I'll just finish this pack and then quit"
You will have already started on a downward spiral if you make that choice
because
you might just undermine your resolve by cutting yourself slack in that way.
It's your quit.
Don't Be Stoooopid.
