Congratulations! Quitting is a big deal and I could add the most difficult thing I've ever done. That being said make a goal for your fitness and you'll see it through. You already proved you have the willpower.
It's a start and you've done well to quit smoking. I do smoke and struggle with my weight, but the best thing is to either drink water before dinner or have lots of raw vegetables as a starter. You eat less then.
First of all...Congratulations on quitting smoking! That's wonderful! You'll get the extra weight off. Just keep at it and you'll feel better in many ways along the way. 👍️🙂
