I've been doing okay with the nic pouches for quitting, almost 20 years at about a pack a day.
I started doing 10 a day, scaling back by two every week, currently at 8/, haven't had a cig in about two weeks and I'll drop it down to 6/ and a lower nicotene dosage on Friday.
Kind of realizing though it's not the smoking itself entirely but the habits around it that I've gotta break; no more waking up, pouring a coffee and having a few smokes in the morning, I usually try to wait 30-60 minutes before popping my first pouch. Things like waiting a bit after meals, not having one before bed etc., are also helping.
I'm already noticing my skin becoming more smooth and no tickle in my throat when I try to sleep.
Not as a health thing since outwardly at least I'm in good shape, not as a money thing since my brand is cheap, but it's just time. I'd like to quit wholesale in 2-3 weeks but even if I can get to a place where I'm using them intermittently, like 1-2 a day, it's a win.
As for drinking I've pretty much had to cut it back to 2 days a week max out of necessity. Can I still drink like I did when I was 23? Yeah I can, more even. What I can't do is drink like I did at 23 and do anything productive before 3 PM the next day or get a full uninterrupted 7 hours.
