I had my last cig January 25 this year. I’m using the Commit nicotine lozenge and weaning off of those. It isn’t easy. I smoked 2 plus packs a day for the last 28 years – that’s a whole lotta time to build up habits and needs. They aren’t going to go away overnight.
I’ve gained 10 lbs. and am having a hard time with that – my back hurts after I get to a certain weight point and I’m approaching it. I have taken to walking strenuously for a half hour or more a day, either in the mall on bad weather days or in cemeteries (no traffic or loose dogs to worry about – very peaceful, actually!). My temper is just barely under control – and I’ve blown a gasket a few times in the past few days. But this too shall pass, as they say.
I too have the trigger problems – the cig with the morning coffee, the smoke after meals, etc. and those are the toughies. Instead I do stretching exercises when I feel that urge.
Welby, if your wife is still smoking, that is going to make it tougher, for sure. The smell gets you drooling for a smoke, just like if you’re on a diet and you walk past the bakery. Take a walk, or go find something else to do for a while. Find something to do with your hands. I took up traditional rug hooking to keep my hands busy – think of all the grand holiday presents I’ll have to give out by the end of the year! 
Really, you can do it. Hang in there!
I had a messy few cigs here and there quit but eventually got done with them. The thing to remember is that the cravings you are having now are precisely the same ones you used to have 20, 30 40 times a day. It is just you used to give in to them. The longer you go without cigs the less regular they become and they last at intense levels for about 10 minutes whether you smoke or don’t. Slurping cold water through a straw can be really helpful.
Hang in there, it really is worth it. You will never know how good it feels until you give yourself a chance.
