I stopped smoking the day my nic+ juice arrived, but that was a decision I made. I ordered 80mL of juice and forced myself to stick through them, even though I didn't like them all.
That said, some folks round here kept smoking analogues for a year+ while vaping. The key is that as you vape more, you'll smoke less, and less tobacco is definitely better than only tobacco.
Recently I got a craving for a smoke, and had one with no regrets. I knew earlier that day I'd end up wanting one because I was going to a party that'd run till the wee hours. I guess I primed myself for it, but whatever, it was a choice and not a need. Funny thing was, after I had that smoke I was actually craving a vape. After a few long pulls, craving was gone.
Needless to say, you're taking the first steps, don't beat yourself up if you keep smoking. Just stick to your guns and you'll push through it. One day you'll not have one, then a week, then a month, next thing you know you'll realize it's been a year.
