I am following your footsteps; you made the third day milestone stares at you in the behind. To me, my third day is eyeballing me, soon enough, I'll leave it in the dust.
However, about going inside the gas station, I would certainly do it, just change your attitude and your thinking. Instead, go in with this senario, pay for your gas and tell the cashier that any other time you would buy smoke, but no more because you quit. You,r really addressing your subconsious not the clerk; Your subconsious needs to hear this, and needs to see your resolve in action, not your fear. Now walk out of the store, smile, you just passed another milestone.
Find a way to celebrate other than puffing, remember N.O.P.E.
My idol you are, lead my way to quiting.
