Oh no!! I mean, it's great that you quit, but... Dealing with withdrawal/ drug cravings with SPD is so insanely bad... And I know EXACTLY what you mean about the smoke breaks. Anytime I'm at a restaurant / social setting, I need to go outside 5 times to smoke a cigarette and de-stress from all the loud and intrusive people in the restaurant. It wouldn't be the same if I just went outside, I'd still be anxious and thinking about the sensory overload inside. I guess for children they can focus on their "chewy" "stuffy" "lovey" "blankey" or whatever to calm them down and avert a meltdown, but there are very few socially acceptable forms for adults besides smoking... Sometimes when I can't go smoke, the bathroom works somewhat okay. As long as no one else is in there it's quiet enough and private enough to calm, cool down, and collect yourself. Keep posting if you find another way!!
