Methods To Quit Smoking

I take a few puffs here and there but I was used to smoking about a pack a day. I’ve gained weight, I experience insomnia, fatigue, depression, my stomach feels unsettled and I feel nauseous often after I eat. Are these normal symptoms?

I seem to eat compulsively and I know it is the result of having stopped smoking. I have heart problems so weight is a health problem for me. I went from waist size 32-33 to a 40.
