I say start cardio like jogging or cycling or boxing and then you will want to not smoke because it messes with the cardio.
I smoke one every morning and sometimes one during the day if I feel bleh and need a little boost. I can and do still box and jog well.
I used to smoke a pack a day and it feels good to be healthy again. I’m working on no smoking but it settles my stomach when I wake up-I wake up vomiting every morning.
I’m on the patch too.
