Pick an activity, any activity! You can walk, run, swim, jog, cartwheel, or hop on one leg, as long as you find a way to move whenever you have a craving. Don’t sit inside and wallow, and definitely don’t wallow with a snack in your hand. If you do this, you will most likely not gain weight when you quit smoking. Just NOT SMOKING doesn’t cause weight gain; that’s a myth! It’s the snacking and depression that some people experience after quitting that causes the pounds to pile on. I personally chose to train for a half marathon. It took about six months, and I ran about 3-4 times a week. At race time, I wasn’t the turtle beating the hare or anything, but I finished, and when I did I was twelve pounds lighter than I was the day I quit smoking. Just sayin’. 
If you’re anything like I was when I quit smoking, your worst fear is how you’ll get through a night at the bar without bumming a smoke from a friend. The answer to avoiding this is not to have a lozenge, a patch, or gum (the patch doesn’t help your fidgeting and the gum and lozenges will clash with the taste of your drink!), but something else - something that will satisfy your busy hands. I’ve seen some people use popsicles or popsicle sticks, but my choice was cinnamon toothpicks. I never even left the house without them. There are candy cinnamon toothpicks that are OK, but in my opinion your best bet is these
