How will my body react when I quit smoking cold turkey?

My smoking is pretty bad. I started in 2004 @ age 19 as a social smoker, now I’m hitting 2 packs a day.

When I quit I want to go to sleep for 8-9 hours so that my body will have a head start on getting it out of my system. BUT, I dread how my body will react. Any idea of what it’ll be like?
**I haven’t had a cig in over 12 hours. I feel exhausted, sore and unmotivated.

Where can I buy a fake cigarette to quit smoking?

Hi! I’m trying to quit smoking, but I believe that my addiction is primarily behavior. I’m looking for a fake cigarette of some kind (Styrofoam, plastic, electronic) that is affordable (no e-cig) and I can buy in person or from a reputable online seller? I’ve found some cigarettes online, from places like Better quit and EZ quit, but the websites don’t look legit. Any ideas?

Thanks!
