Have one.
If they still mean that much to you ,then just have one - oh wait, what?! I'm advocating giving in?!!8-o
Yeah - I am - if your body is jonesing that bad, having ONE can mean the difference between failing utterly and taking longer to leave em all behind. Why add to the stress with guilt?
I didn't quit right away.
I had no intention of quitting period. I liked at least 5 of my daily 20. The first one, the one after meals, the one with coffee that I kicked back on, the one before bed. They were all great - the others tasted like stewed socks and made me feel like poo. It seemed though, that I couldn't have the 5 (or 4) without having hte other 15 though.
With the PV, my plan was to use it to replace the 15 I hated.
Odd thing though, I started having less.
First day I had 10, then 10 again the next, then 8, then 4, then 2..then none. The urge just left me. I wanted my PV ALL the time - having a cig actually seemed a waste of vaping time

At NO point did I tell myself I couldn't have any. I still have a pack someplace, in a drawer I think. If I want one, I'll have one. But the thing is, I don't want one.
I'm wary of upping nic levels too far - nic can react badly to people - give them headaches, stomach issues, feelings of anxiety. I know some people swear by it, but I'm perhaps more cautious.

I'd have one, don't deny yourself and don't feel like you're depriving yourself. Don't allow the ciggies to have any power over you; that's how ex-smokers become smokers again.
Quit at a pace you're comfortable with, if quitting is what you want to do.
And good luck!
