Methods To Quit Smoking

I have started working out really hardcore and I want to start running again, but I just quit 2 days ago and still feel severe pain in my chest. I know I need to give it awhile but how long can you predict?

I started on step 2 because i don’t smoke that much although I have been smoking for about 10 years. I feel awful. I couldn’t sleep and had tons of bad dreams. I am hot and shaky and nauseous. I have used the patch before but didn’t feel like this. Is this normal?

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 quit smoking a few weeks ago, and lately I’ve been experiencing some tightness in my chest and it is quite uncomfortable. I was just wondering if this could be attributed to my lungs attempting to heal themselves, or whether I should be concerned. You answers are much appreciated, thank you.

quit smoking like 10 days ago and now it’s been two days I have a terrible headache at the front area of my head (forehead, especially between my eyebrows) and I have runny nose (sometimes it gets stuffy)
Does quitting smoking has anything to do with this ?

It just so happens that I’m trying to quit smoking and I’ve noticed that I’ve gained about 12 pounds.
