To OP: please find a substitute activity these next few months.
When I quit some 30 years ago, my substitute activity was going to the mall. I lived in Northern Iowa
Where it was cold and snowy, so walking the long shopping mall got me out of the house and active. During that time I spent $1,000 on clothes. But that was my activity…walking, shopping, more walking.
I did not gain weight (although if you gain weight it’s not a big deal. You can take it off later.) That $1,000 was money well spent.
So many Hollywood people smoke, it keeps their weight down, but you don't hear about that. One time when I posed with a photograph with a celebrity who came to town for a charity promotion, she was smoking and she put her cigarette behind her back for the photographs. She said oh we’re never photographed with a cigarette!
