Not his first attempt, but I want to do whatever I can to encourage him to stay on the wagon this time. I don't have any experience of this, so I'd appreciate any tips from those who have been there already.
The cravings come in waves, so I guess the best thing you can do when you are around, if he seems to have the craving, is to try to distract him, maybe learn a few jokes you can fire off. Whatever distraction will work for a while.
Personally I quit by switching to vapes, and then after years of vaping, I decided to quit that too. Quitting vaping seemed easier, as I could decrease the nicotine, and continue to vape. Took me 3 months to quit.
From smoking to vaping to nicotine gum was my approach. Managed to keep to the gum until travelling, doing the cycle again now. Maybe offer nic gum if cravings hit OP? Idk, everyone's different though
