That's really great, especially coming from where you were smoking. If you're comfortable with the habit of using a vape and not requiring nicotine to stay off cigs, that's certainly the way to go. My only advice is have some 3 or 6 mg juice around the house anyway. Should you ever hit a rocky or stressful patch in the future and be tempted to pick up a cigarette, that might well prevent you from jumping back into tobacco use. Hopefully that will never happen.
