We had some movers relocate some large items 2 miles away and I was in charge of the move.
For the heaviest items (a 300+ pound solid oak roll top desk that I had to remove the sliding glass door to get it through) they had to work together.
I noticed they would stop to make sure the other person was ready to make the effort at that moment, and then, they would push forward.
When you quit smoking, there is no other person.
You are it. You need to stop in that moment, get your balance back, and, REALLY decide what's going to happen next. If you are in public, excuse yourself and walk away for a few minutes.
Regain your balance. Move Forward.
You are it!
