I put on about 10 pounds pretty quickly after I quit and had to work to get rid of it. It's a twofold problem: Most of the evidence points to nicotine having at least a minor impact on suppressing appetite. But I think most of the weight gain is caused by turning to other crutches to help get over the cravings. Most people who quit smoking snack more. I did. For that first month or two when I wanted a smoke I had something else instead, usually chips or chocolate. If you're used to smoking a pack a day and instead have 20 pieces of chocolate a day it's pretty easy to see how you might pack on a few pounds.
that is next on the agenda. My brother Mel quit and uses Cinnamon sticks like a cig. It works for him and to quote my brother on smoking, "I quit the only thing I was really good at"...LMAO!
