Discard your butts now in a way that they're not usable. Trust me, they may start looking really attractive later and you know there's a puff or two left...
With the weather, you're going to be disinclined to go out. That's good and it'll help.
Other than that, vape a lot, and vape before you feel the need for nicotine--just for a few days. Try to train yourself out of the need/smoke cycle. It helped me out a lot, and I eventually stopped associating nicotine with cigarettes. My vape had what I wanted!
Some of us do take longer and do have the occasional cigarette during the transition. There's really nothing wrong with that. So I don't have any issue with it if you do smoke, just so long as you're smoking less this week than you did last week. It took me three months to make the full switch and trying out about thirty different things.
