I'm only a few days into it, but I'm picking it up as I would my smokes - every few hours. I notice that once my daughter goes to bed, I cart it with me to my computer and vape here and there sporadically, which is what I'd wanted to do with the cigs, but couldn't because I refused to smoke inside. I do vape outside when my daughter is awake. My husband still vapes outside even after daughter goes to bed.
I was a 1pack a day smoker, but I haven't even gone through an entire 10ml juice yet. (It's a 12mg nic I think.) I did have some horrible withdraws Friday morning ... until I asked my co-worker/friend if I could take a hit of her cigarette. I can only imagine the face I pulled as I quickly handed it back and puffed furiously on my PV.
